Answer to Question #297221 in General Chemistry for Loti

Question

Calculate the volume of CO2 measured at STP that can be obtained by the thermal decomposition of CaCO3 by the equation:

CaCO3=CaO+CO2

Answer 1

PV = nRT

$P=$ 1 atm

$n=$ 1 mole

$R=0 .08205L$ atm mol$^{-1}K^{-1}$

$T=273K$

$\therefore\>V=\frac{1×0.08205×273}{1}$

$=22.4Litres$
