Question

An organic salt gave the following percent composition :
Na=29.11%
S =40%
O=30.38%
Calculate the empirical formula of the salt?

Answer 1

the answer is 99.49
( 29.11+40+30.38) =99.59

Answer 2

for Na= 29.11/23= 1.26

for s = 40.50/32=1.26

for o = 30.38/16=1.89

here, simplest ratio is by dividing three by smallest value,

na= 1  ,s=1,  o=1.5

whole no. ratio =2:2:3

hence emperical formula is na2s2o3
