Question

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/cm3, what is the mass of the fuel in kilograms?

Answer 1

1 L ------- 1000 cm³
1.45 L ----- ???

1.45 * 1000 = 1450 cm³ ( volume )

Density = 0.710 g/cm³

mass = in Kg

m = D * V

m = 0.710 * 1450

m = 1029.5 g

1 Kg ------- 1000 g
kg -------- 1029.5 g

mass = 1029.5 / 1000

mass = 1.0295 Kg

hope this helps!
