Question

how many grams of CO2 can be generated according to given equation: CaCO3 (s) +2HCl (aq) - CaCl2 (aq) +H2O (l) +CO2(g)

Open in App

Solution

Molecular wt. of CaCO₃ = 100g
Molecular wt. of CO₂ = 44 gram
According to above equation 44 g of CO₂ will generate if 100 gram of CaCO₃ will react.
