equal masses of so2 and o2 are kept in a vessel at 27 degrees celcius. the total pressure of the mixture is 2.1atm. the partial pressure of so2 is

Answer 1

Make up masses--any convenient number will work.
mols SO2 = grams/molar mass = ?
mols O2 = grams/molar mass = ?
Total mols = ?

XSO2 = mols SO2/total mols.

Then pSO2 = XSO2*Ptotal

Answer 2

0.7 atm

Answer 3

How 0.7

Answer 4

Pso2=xsomultiply ptotal
Ptotal=2.1atmwso2=wo2xso2=nso2di
