how many moles NaHCO3 in 16.8 g?
each mole occupies 22.4 L, right?
What will be the volume of Co2 at NTP obtain by heating 16.8gm NaHCo3

No. 1 mol of gas occupies 22.4 L @ STP but 1 mol of gas occupies 24.0 L @ NTP (STP uses 273 for T and NTP uses 293 for T).
Also note that 1 mol NaHCO3 produces either 1 mol CO2 or1/2 mol CO2 depending upon the degradation of the NaHCO3.
2NaHCO3 ==> Na2CO3 + CO2 + H2O or
2NaHCO3 ==> Na2O + 2CO2 + H2O
