				   2.2g of a compound of phosphorous and sulphur has 1.24g of P in it.Determineits empirical formula.

7 years ago


Answers : (2)



Given mass


Atomic mass


Mole ratio

Whole no. ratio















So the empirical formula is P13S10

7 years ago

atomic weight of P : 31  and S :32

wt of P:1.24g and wt pf : 0.96g

ratio of moles of P:S = (1.24/31) : (0.96/32)

                                     = 4:3

empirical formula is : nP4S3
