The reaction equation must first be put down and the stiochiometry is used to calculate the mass of the bicarbonate produced as 0.11 g.
A reaction refers to the transformation of reactants into products. We have the equation of this reaction as;
CO2 + H2O ---->H2CO3
If 1 mole of CO2 gas occupies 22400mL
x moles of CO2 occupies 40 mL
x = 0.0018 moles
If 1 mole of CO2 yields 1 mole of bicarbonate
0.0018 moles yields 0.0018 moles of bicarbonate
Mass of bicarbonate = 0.0018 moles * 61 g/mol = 0.11 g
