A student decided to undertake a balance calibration exercise during a lab session involving burette calibration. He found the apparent weight of calcium carbonate in air to be 100 grams and density to be 1.33g/mL. Assume that the standard steel weight used in the calibration has a density of 8.0g/mL and air has a density of 0.0012g/mL. What would be the true mass of the calcium carbonate sample?
2. Retort Distillation Apparatus usually used to measure water and oil saturation. Analyzing the
sample using this technique usually will take less than one hour (This is one of the most
important advantages -Rapid), however the disadvantages of using this technique that we
can't use the sample anymore because it will destroys as result of high temperature.
You are a lab engineer and you managed to recover 4.32 and 1.91 ml of oil and water, respectively
from this technique. If the bulk volume was 34.98 ml and the grain volume was 26.34 ml. determine
the following:
A. Saturation of gas
B. Saturation of oil
C. Saturation of water
II.
BOILING POINT ELEVATION:
The temperature of a boiling 50 mL of distilled water in an Erlenmeyer flask with a small
flame was taken to be 98°C. The bulb of the thermometer must not touch the bottom or sides
of the Erlenmeyer flask.
In another Erlenmeyer flask, 2.83 grams of urea is dissolved in 10 grams of distilled water. The
solution was let to boil gently and its boiling point was recorded to be 101°C.

- Hexane (C6H14, density = 0.766 g/cm3), perfluoro-hexane (C6F14, density = 1.669 g/cm3), and water are immiscible liquids; that is, they do not dissolve in one another. You place 10 mL of each in a graduated cylinder, along with pieces of high-density polyethylene (HDPE, density = 0.97 g/cm3), polyvinyl chloride(PVC, density = 1.36 g/cm3), and Teflon (density = 2.3 g/cm3). None of these common plastics dissolves in these liquids.

The mass they observed was unstable, constantly jumping between 39.5 and 41.5. Choose all of the following reasons that could cause this error. O The doors to the analytical balance were not closed completely, allowing an air current to circulate inside the balance. One weigh boat was used to tare the balance while a different one was used when the sample was massed. Twice the amount of sample was placed on the analytical balance. O The sample was heated, causing a convective flow.arrow_forwardTom, a scheduler at Mangel-Wurzel Transport, gets a call from a regular customer needing to move 15.8 m² of rock and soil, which Tom knows from previous experience has an average density of 740 kg/m³.

Its decomposition may be represented by 4C3H3N3O9 → 6N2 + 12CO, + 10H20 + O2 This reaction generates a large amount of heat and gaseous products. It is the sudden formation of these gases, together with their rapid expansion, that produces the explosion. ok (a) What is the maximum amount of O, in grams that can be obtained from 7.50 × 10² g of nt nitroglycerin? g ences (b) Calculate the percent yield in this reaction if the amount of O, generated is found to be 24.5 %arrow_forwardA chemist analyzes a sample of iron ore furnished by the National Institute of Standards and Technology, NIST.

- A group of students were trying to experimentally determine the density of an unknown liquid. They developed a standard technique for measuring density by recording the mass of a liquid using an analytical balance. The volume of the liquids were accurately measured using a serological pipette and was recorded to be 5.00 mL for each trial. The students were able to collect the following data: LIQUID Trial 1 (mass in Trial 2 (mass in Trial 3 (mass in Theoretical SAMPLE grams) grams) grams) Density Hexane 3.281 3.284 3.279 0.655 g/ml Acetone 3.921 3.923 3.947 0.784 g/mL Ethanol 3.912 3.911 3.913 0.789 g/mL unknown 3.914 3.911 3.910 Using the calculated experimental average density of the liquid samples as reference, what is the probable identity of the unknown? ethanol heхane acetone cannot be determinedarrow_forwardArchimedes, a famous Greek scientist, was given a problem by King Hieron II of Syracuse (Sicily).

As the shopping trip progressed, the cart increased in mass from 0 kg to 10 kg. Which argument below supports Raymond's claim that it was more difficult to push the 10 kg cart as opposed to the empty cart. O As the cart decreased in mass, Raymond had to use more force to push the cart. O As the cart increased in mass, Raymond had to use more force to push the cart. O As Raymond continued to push the cart during the duration of the trip, he became tired which made it more difficult to push the cart. O As Raymond continued to push the cart during the duration of the trip, friction began to build up on the wheels causing the cart to be more difficult to push.arrow_forwardYou try your best to put your samples in the middle of the balance pan when you try to weigh them every time. However, you know that it is impossible to place your samples in the same location each time. This discrepancy introduces error to your measurements. systematic randomarrow_forward
