HELLO VINAY,
Understand this reaction first.
2 CaCO3 + 2H3PO4 -------------> Ca3(PO4)2 + 3CO2 + 6H2O
one thing you have to know that 2CaCO3 is the limiting reagent in this reaction
1 mole of CaCO3 requires 2/3 mole of H3PO4
SO,
for,,,
0.1 -----------------> 0.2/3
so it is limiting
So 0.1 moles of CO2 will be evolved
So 0.1 X 22.4 = 2.24Litres of CO2
THANK YOU
