Question

When two molecules of methanol (CH3OH) react with oxygen, they combine with three O2 molecules to form two CO2 molecules and four H2O molecules. How many H2O molecules are formed when 94 methanol molecules react

Answer 1

188

Step-by-step explanation:

For every 2 molecules of methanol reacted, 4 molecules of water are formed. Use this relationship to solve.

2/4 = 94/x

2x = 376

x = 188

188 molecules of water will be formed.
