Propane, c3h8, is commonly provided as a bottled gas for use as a fuel. in 0.200 mol of propane: (show all your work)

a. what is the mass of propane

The mass of 0.200 moles of Propane is calculated as follow,

Data Given:

Moles = 0.200 mol

M. Mass = 44 g/mol ∴ C₃ = (12 * 3 = 36)

H₈ = (1 * 8 = 8)

C₃H₈ = 44 g/mol

Formula Used,

Moles = mass : M. mass

Solving for mass,

Mass = Moles * M. Mass

Putting Values,

Mass = 0.200 mol * 44 g/mol

Mass = 8.8 g

The molar mass of propane is C₃H₈ - (12x3) + (1x8) = 44 g/mol

This means that 1 mol of propane weighs 44 g

The number of moles of propane present - 0.200 mol

1 mol weighs - 44 g

Therefore 0.200 mol of propane weighs - 44 g/mol x 0.200 mol = 8.8 g

Mass of propane present - 8.8 g
