Homework Help: Chem

Could someone please walk me through step by step on how to do this.

Propane (C3H8) burns in oxygen to produce carbon dioxide and water.
C3H8(g) + 5 O2(g) 3 CO2(g) + 4 H2O(g)

Calculate the mass of CO2 that can be produced if the reaction of 48.2 g propane and sufficient oxygen has a 62.3% yield.

In Grams

You have the equation. Follow the steps in a sample problem I posted here.

When you have the final mass CO2, multiply by 0.623 to correct for it not being a 100% yield.
