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, how many kilograms of fuel are contained in one canister?

the canister contains a gas used to fuel a burner

the volume of the white gas to be used is - 1.45 L

density of white gas is 0.710 g/cm³

density is defined as the mass per unit volume

the mass of 1 cm³ of white gas is - 0.710 g

1 cm³ is equivalent to 0.001 L

the volume given is in Litres

so if 0.001 L has a mass of 0.710 g

then 1.45 L have a mass of - 0.710 g / 0.001 L x 1.45 L = 1030 g

since 1000 g is equivalent to 1 kg

mass of white fuel is - 1030 g/1000 g/kg = 1.03 kg

theres 1.03 kg of fuel in one canister

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
