Q1. The mass of fuel in a jet must be calculated before each flight to ensure that the jet is not too heavy to fly. A 747 is fueled with 173,231 L of jet fuel. If the density of the fuel is 0.768 g/cm^3, what is the mass of the fuel in kilograms?

Conversion factors:

1 mL = 〖10〗^(−3) L
1 mL = 1 cm3
d = 0.768 g/cm^3
1000 g = 1 kg

Q2. Backpackers often use canisters of white gas to fuel a cooking stove’s burner. If one canister contains 1.45 L of white gas and the density of the gas is 0.710 g/cm^3, what is the mass of the fuel in kilograms?

Q3. A drop of gasoline has a mass of 22 mg and a density of 0.754 g/cm^3. What is its volume in cubic centimeters?
