I2O5(s) + 5CO(g) → I2(s) + 5CO2(g)

1 mole of any gas occupies 22.4 L at STP.

Proportion:

1 mol – 22.4 L

x – 30 L

"x = \\frac{1 \\times 30}{22.4}=1.34 \\;mol"

n(CO) = 1.34 mol

According to the reaction:

n(I2) "= \\frac{n(CO)}{5} = \\frac{1.34}{5} = 0.268 \\;mol"

"m = n \\times M"

M(I2) = 253.8 g/mol

m(I2) "= 0.268 \\times 253.8 = 68.02 \\;g"

According to the reaction:

n(CO2) = n(CO) = 1.34 mol

M(CO2) = 44.01 g/mol

m(CO2) "= 44.01 \\times 1.34 = 58.97 \\;g"
