Question

Calculate mass and volume of oxygen required at stp to convert 3.2 kg sulphur into so2

Answer 1

S+O2-----------SO2
32g of sulphur rqd O2=32g
1g of sulphur rqd. =32÷32=1g
3.2g of sulphur rqd= 3.2×1=3.2g
Now
32g of sulphur rqd volume=22.4L
1g of sulphur rqd volumeO2=22.4÷32
3.2g of sulphur rqd volumeO2=22.4÷32×3.2=2.24L
