33.6L of CO2

Explanation:

First write the equation

2NaHCO3Na2CO3(s)+CO2(g)+H2O(l)

The mole ratio of reactant : product(CO2)
= 2mol : 1mol
Solve for ratio
Amount of CO2 formed in moles =

3mol : x = 2mol : 1mol

3 and x should be in the proportion so that 3x=21

Remember
products of means = product of extremes

3:x=2:1

Or 2x=3×1

x = 1.5mol

Volume of 1mol at STP = 22.4L
Thus volume of 1.5mol at STP

=1.5mol×22.4L=33.6L
