Answer 1

Favorite Answer

At STP, one mole of any gas or gram molecular weight of any gas occupies 22.414 liters.

Gram molecular weight of CO2 is 44 g.

So 44 g of CO2 will occupy 22.414 liters

and thus 15 kg will occupy 22.414 X 15000/44 liters which is approx. 7641 liters

Answer 2

What you should know: 1 kg=1000g

15 kg CO2 x(1000 g CO2/kg CO2) x(mol CO2/MM CO2) x(22.4 L CO2/mol CO2)= ANS

Refer to periodic table for weight of CO2 fill in for MM and compute the expression
