2.2 g of a compound of phosphorous and sulphurhas 1.24 g of P' in it. Its emperial formula is(1) P2S(3) P S(2) P S(A) P Ss

Answer»

option (d) is correct.

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
