- Heptane and water do not mix, and heptane has a lower density (0.684 g/mL) than water (1.00 g/mL). A 100-mL graduated cylinder with an inside diameter of 3.34 cm contains 36.7 g of heptane and 35.3 g of water. What is the combined height of the two liquid layers in the cylinder? The volume of a cylinder is π r2h, where r is the radius and h is the height.arrow_forwardHeptane and water do not mix, and heptane has a lower density (0.684 g/mL) than water (1.00 g/mL). A 100-mL graduated cylinder with an inside diameter of 3.00 cm contains 29.7 g of heptane and 36.4 g of water. What is the combined height of the two liquid layers in the cylinder in cm? The volume of a cylinder is π r2h, where r is the radius and h is the height.arrow_forward1a. Diamond, graphite, and copper have very different properties but are made of networks of atoms. List the properties of each below in the table.

- The level of water in an Olympic size swimming pool (50.0 meters long, 25.0 meters wide, and about 2.00 meters deep) needs to be lowered 8.00 cm. If water is pumped out at a rate of 3.40 liters per second, how long will it take to lower the water level 8.00 cm?arrow_forwardA chemist bought a small piece solid figurine suspected to be gold. Knowing that gold has a density of 19.3 g/cm^3, he chemist decides to determine its density. The figurine is put into a graduated cylinder that contains 32.6 mL of water. The reading with the figurine in the water is 45.2 mL. The mass of the figurine is 225.1g. Is the figurine made of pure gold? explain your reasoning.arrow_forwardOn average, water flows over a particular water fall at a rate of 2.03 x 105 cubic feet per second. One cubic foot of water weighs 62.4 Ib. Calculate the rate of water flow in tons of water per day. (1 ton = 2200 lb) tons/dayarrow_forward
- Human fat has a density of 0.918 g/cm^3. How much volume (in cm3cm3) is gained by a person who gains 12.5 lb of pure fat?arrow_forwardA student finds that 24.96 g of water at 24.9 C(density=0.9971 g/cm3) is required to completly fill an empty flask. The water is removed and completely dried; granular solid copper weighing 51.24g is then added to the flask. With the copper present in the flask, it was determined that 19.24 g of water was required to fill the remaining space in the flask completly 1.) volume of the empty flask 2.) volume of the copper 3.) density of the copperarrow_forwardSuppose some measurements are made on two different homogeneous stones to find out if they are made of the same kind of rock. The mass and volume measurements are listed below. Are the two stones the same type of rock? Why or why not? Show all calculations.

- A chemist mixes two liquids, A and B, to form a homogeneous mixture. The densities of the liquids are 2.0514 g/mL for A and 2.6678 g/mL for B. When she drops a small object into the mixture, she finds that the object becomes suspended in the liquid; that is, it neither sinks nor floats. If the mixture is made of 41.37 percent A and 58.63 percent B by volume, what is the density of the metal?
