NaCl + H2O + CO2 + NH3 ______> NaHCO3 + NH4Cl

Question

1) You dissolve an excess of NaCl in a solution containing 50.0 mL of 4.77 M ammonia. You bubble in an excess of CO2.
Calulate the theoretical yield of sodium bicarbonate.

I have no idea how to do this, can I know the step by step procedure?

Answer 1

The amount of NaHCO3 depends only upon the starting amount of NH3.
1. You have the equation. Make sure it is balanced. If not, balance it before going further.
2. Convert NH3 to mols. mol = M x L = ?
3. Using the coefficients in the balanced equation, convert mols MJ3 to mols NaHCO3.
4. Convert mols NaHCO3 in step 3 to grams. g = mols x molar mass = ? This is the theoretical yield.

I think the answer is about 20 g but you should check me out on that.
