A 3.23 liter glass bottle is full of oil. Assume it contains 3.23 L of oil. The density of oil is 1.23 g/mL. The glass bottle itself has mass of 287 grams. What is the weight of bottle plus oil in pounds? This is similar to question 11 in 'some extra questions' in module. You need to write your ansver in the box with two numbers past the decimal. Please don't worry about the sig figs in this case--in these formula problems, the Canvas software will give a variety of questions and each student gets their data with different sig figs. So I just have to choose and sometimes it might seem that two past the decimal is not the correct sig figs. Nonetheless, you have to follow that direction.

A beaker of water has an initial mass of 455.2 g. After it has been left uncovered for several days, some of the water has evaporated. The new mass of the beaker is found to be 422.55g using a more precise balance. Which of the following expresses the mass of the evaporated water using the correct number of significant figures? A) 32.65 g B) 32.7 g C) 33 g D) 32.650 g
The mass of a sample is measured by difference: first the mass of a beaker is measured (43.55 g), and a small amount of the sample is added to the beaker. The mass of the sample plus beaker is then measured to be 77.169 g. The mass of the sample should be reported as

In lab, an empty weigh boat measures 11.2 g. A piece of metal is added to the weigh boat, and the total mass increases to 19.9 g. A graduated cylinder is filled with 24.5 mL of water. The piece of metal is carefully added to the graduated cylinder, and the volume increases to 28.2 mL. Using this data, find the density of the piece of metal, in units of g/mL.
1. A hollow square metal tube has a measurement of 2.42 in for each side and a weight of 53.71 g. The volume of empty space inside the tube was measured to be 0.93 in3. If the density of the metal used in constructing the tube is 11.81 g/mL, calculate the length of the tube in inches. 2. Porosity is a measure of the void or empty spaces in a material and is a fraction of the volume of voids over the total volume. The density of the solid material used to create 6 pieces of 0.99 cm diameter and 1.17 cm height cylindrical beads is determined to be 1.84 g/mL. These beads were then placed in a flask and were filled to the 43 mL mark with a salt solution. The total weight measured of the beads and the salt solution was 47.22 g. Upon further inspection, it was found that manufacturing defects caused the measured porosity of the beads to be at 20%. Assuming that the solution was able to fully fill the empty spaces inside the beads, calculate the density of the salt solution. 3. A chocolate…
