Title: Mole to Mole Conversions
Post by: [TribalFox] on February 26, 2009, 11:10:24 AM

How do you work this problem out?

2C₁₈H₃₈ + 55 O₂  :rarrow: 36 CO₂ + 38 H₂O

A) if you had 8.5 moles of wax how many moles of carbon dioxide could be produced?

B) if you want .30 moles of carbon dioxcide how many moles of oxygen will be used up?

C) How much wax would you need to produce 83.6 moles of water?

D) How many moles of water would be produced from 4.56 moles of oxygen?

Follow the stoichiometric ratio.
