Volume at n.t.p of 0.22 g of co2 is same as :

2

At N.T.P 1 mole of CO2
gas =22.4L
Mass of 1 mole of CO2
gas= 44g
44g of gas= 22.4L
therefore 0.22g of gas = 0.22/44 moles= 0.005 moles
Volume= (22.4/44) X 0.22L= 0.112L
similarly
Molar mass of hydrogen gas = 2g
0.01 g of hydrogen gas = 0.01/2= 0.005 moles
Therefore volume = 22.4X 1/200 = 0.112L
Molar mass of ammonia= 17 g
0.085g= 0.085/17=0.005 moles
1 mole - 22.4 L
therefore 0.005 moles = 0.112 L
Molar mass of SO2
= 64g
320mg= 0.32 g= 0.32/64 = 0.005 moles
1 mole - 22.4 L
therefore 0.005 moles = 0.112 L
Hence all of the above are correct
