in both cases, write the equation.
Figure how many moles of the limiting reactant you have
The equation will tell you how many moles or product to expect
convert that back to grams
For #2, just work backwards. The key is to change everything to moles, and make sure the equation is balanced right.
1.) 22.5 grams of Potassium nitrate react with Sodium Bromide to produce how many grams of
Potassium Bromide?
