A leavening agent used in some older recipes is baking ammonia or ammonium bicarbonate. As it is heated, it breaks down into three gases- ammonia, water, and carbon dioxide. For each 20g of baking ammonia heated, how many grams of carbon dioxide are released?

1. (NH4)2CO3 ==> 2NH3 + CO2 + H2O

Convert 20 g (NH4)2CO3 to moles. moles = g/molar mass

Using the coefficients in the balanced equation, convert moles ammonium carbonate to moles CO2

Convert moles CO2 to grams. grams = moles x molar mass.

2. Sorry but I misread the bi part of ammonium bicarbonate.
The equation should be
NH4HCO3 ==> NH3 + CO2 + H2O
Check that to make sure it's right.
The remainder of the original post is ok.
