Density Problems #1 On a separate sheet of paper, solve for the following problems. Make sure to SHOW YOUR WORK. 1. A sample of ocean water weighs 158 g and has a volume of 156 ml. What is its density? (1.01 g/ml) 2. A cylindrical box with a volume of 200.0 cm3 holds 432.0 g of NaCl. From this information, calculate the density of the NaCl. (2.16 g/cm3) 3. The salt is emptied out of the box described in problem 3. Sugar is now used to fill the box. The mass of the sugar used is equal to 316.0 g. What is the density of sugar? (1.58 g/cm3) 4. What is the volume of helium found in a balloon with a mass of 0.890g. The density of helium is 0.178 g/L. (5.00 L) 5. Calculate the density of ammonia gas from the information that 8.9 L of the gas weights 6.86 g. (0.77 g/L) 6. What volume of silver metal will weigh exactly 2500.0 g? The density of silver is 10.5 g/ml. (238.10 ml) 7. The hydrogen gas stored inside a large weather balloon weighs 13.558 g. What is the volume of the balloon if the density of hydrogen is 0.089 g/L. (152.33 g) 8. A block of lead has dimensions of 4.5 cm x 5.2 cm x 6.0 cm. The block weighs 1587 g. Calculate the density of the lead. (11.30 g/cm3) 9. A rubber balloon weighing 144.85 g is filled with carbon dioxide gas and reweighed. The weight of the balloon and gas is 153.77 g. The volume of the balloon filled with carbon dioxide is 4.55 L. What density do these data yield for carbon dioxide? (1.96 g/L) 10. A cylindrical glass tube of length 27.75 cm and a radius of 2.00 cm is filled with argon gas. The empty tube weighs 188.25 g. The tube filled with argon weighs 188.87 g. Use this data to calculate the density of argon gas. (1.78 x 10-3 g/cm3) Density Problems #2 On a separate sheet of paper, solve for the following problems. Make sure to SHOW YOUR WORK. 1.
