Question

find the total molecules from the following data
4.4 grams of CO2+5.6 litres of N2+12.8 grams of SO2+64 grams of O2+4.48 litres of H2...plz help me

Answer 1

4.4gm CO² means 4.4/44 moles of CO² = 0.1 mole

At STP, 22.4 liters of any gas is equivalent to 1 mole of that gas. Hence, 5.6 liters of N² means 5.6/22.4 = 0.25 moles of N²

Molecular mass of SO² = (32+16×2) = 64 gm/mole. So, 12.8 gm of SO² means 12.8/64 = 0.2 moles of SO².

Molecular mass of O² = 32u
So, 64 gm of O² means 64/32 = 2 moles

Again, 4.48 liters of H² means 4.48/22.4 = 0.2 moles of H²

Overall....it is (0.1+0.25+0.2+2+0.2) = 2.75 moles.
