As there is no equation given, so let me give my own equation and answer the question,
NaHCO₃ + HCl → NaCl + CO₂
According to this equation,
58.4 g NaCl is produced along with = 44 g of CO₂
Then with the production of...
75.00 g of NaCl = X g of CO₂ will produce
Solving for X,
X = (75.00 g × 44 g) ÷ 58.4 g
X = 56.50 g of CO₂
