Propane has the formula C3H8\text{C}_3\text{H}_8C3H8.
Calculate the mass of carbon in 150 g of propane.
Give your answer to three significant figures.
(Relative atomic masses: H=1.0\text{H} = 1.0H=1.0, C=12.0\text{C} = 12.0C=12.0; Relative formula mass: C3H8=44.0\text{C}_3\text{H}_8 = 44.0C3H8=44.0)
You must show your working.
