Question

calculate the volume of O2 required at stp for complete combustion of two moles of carbon disulfide which produce CO2 and and so2​

Answer 1

Hi there,

♤ CS2 + 3 O2 => CO2 + 2 SO2

◇ According to the equation we need 3 mols of oxygen for complete combustion of one mole carbon disulfide

☆ So, 2 mole carbon disulfide requires 6 mol of oxygen gas

☆ At stp, one mole of gas occupies 22.4l volume

● So 6 mole of oxygen gas occupies

6×22.4 = 134.4 l
