Pre-Lab Study Questions 1. What property of oil makes it float on water? Water hasmare density than oil There is more water mass than oil per unit volume 2. Why would heating the gas in a hot air balloon make the balloon rise? Because there is hot oir inside the baloon (from the heater/) and it makes is less dense than the air of the outside the bala 3. What is the difference between density and specific gravity? Ratios of each other. Density is the measure of the amount of mass per volume. Specific gravity is a measco of density relative to the density of a reference substance 4. An object has a mass of 18.4 g and a volume of 11.2 mL. a. What is the density of the object? p = m b. What is the specific gravity of the object? c. Will the object sink or float in water? Object will sink 18.49 11.2mL = 1.6 g/mL olensity of substance g/mL density of water 15.09 V = 0.875 g/mL 8 It is a number with no whit 1.00g/mL b. What mass, in grams, of the liquid is in 34.6 mL of the liquid? m (g) of liquid volume (m²) of liquid = 5. A 15.0 g-sample of a liquid has a density of 0.875 g/mL. a. What is the volume, in milliliters, of the liquid? Use conversion factors to calculate answer. = 17.1mL 30.3g 1.6gmL 1.00g/m = 1.64
