Question

how mole of oxygen atoms are there in 89.6 dm3 of SO2 at STP,??????? ​

Answer 1

Answer:

4O2 4mol o2 is needed

Explanation:

by pv=nrt

1dm3=1L

at stp pressure is 1atm , temperature is 273k

89.6×1=n×0.0821×273

89.6=22.4L×n

n=4 mol

s+o2 = so2

s+o2=4so2

4S+4o2=4SO2

so to make 4 mole SO2 we need 4mol o2

1molSO2 needs 1mol o2

Answer 2

Answer:

22.4=89.6

2=X

So 2×89.6/22.4= 8
