How many grams of NaCl would be formed from 100 grams of Na2CO3 in the following reaction?

Question

Na2CO3 + 2 HCl → 2 NaCl + CO2 + H2O

Answer 1

Na2CO3 + 2 HCl → 2 NaCl + CO2 + H2O
mols Na2CO3 = grams/molar mass = 100/106 = approx 0.9 but that's an estimate.
From the equation 1 mol Na2CO3 will produce 2 mols NaCl; therefore you will get approx 2*0.9 = estimated 1.8 mols NaCl
Redo the calculations and convert mols NaCl to grams this way. grams NaCl = mnols NaCl x molar mass NaCl = ?
Post your work if you run into trouble.
