The molar mass of carbon dioxide (CO2) is 44.01 g/mol. The molar mass of water (H2O) is 18.01 g/mol. A reaction uses 528 g of CO

Black_prince [1.1K]

CO₂ + H₂O -------> H₂CO₃

moles of CO₂ = $\frac{MASS of Carbon}{ MOLAR MASS}$

= $\frac{528 g}{44.01 g / mol}$

= 11.997 mol

mole ratio of CO₂ : H₂O =   1 : 1

  ∴ moles of H₂O = (`11.997 mol ) * 1
= 11.997 mol
   ≈ 12 mol
