find the volume of CO2 at NTP obtained on heating 4.2g of NaHCO3 find the volume of CO2 at NTP obtained on heating 4.2g of NaHCO3
2NaHCO3 = Na2CO3 + CO2 + H2O2 moles of NaHCO3 = 1 mole of CO24.2 / 84 mole of NaHCO3 = 4.2 / 168 mole of CO2 = 0.025 moles of CO2wt. = mol. wt. * moles = 44 * 0.025 = 1.1gm
