Approx. 20*g of stuff.......

Explanation:

We follow the stoichiometric equation.....

CaCO_3(s) +Delta rarr CaO(s) +CO_2(g).

We know that under standard conditions of temperature, and pressure, 1*mol of Ideal Gas occupies a volume of 25.4*dm^3; you will have to fill in the appropriate standard according to your syllabus.

And thus mass equivalence of SOLID CALCIUM CARBONATE.....

=(5.6*dm^3)/(25.4*dm^3*mol^-1)xx100.09*g*mol^-1=??*g
