Mass to Mass Calculations
Rules
1) Balanced Chemical Equation
2) Write down known amounts under each chemical
3) Put a ? and unit by chemical in question.
4) Do “stoich” line to determine amount
Example 1:
If 12.3 mol of KClO
reacts: How many mol of O
will be formed?

2 KCl + 3O
2KClO

Example 2:
If 4.53 g of KClO
reacts: How many mol of O
will be formed?
