Work Step by Step
We have 10.4% C, 27.8% S and 61.7% Cl.
First we assume 100g basis to make the masses easier. Then we have
10.4 g C, 27.8g S and 61.7g Cl
Now we need to convert to moles so we have
C is 12g/mol so 10.4g is 0.866 mol
S is 32 g/mol so 27.8g is 0.866 mol
Cl is 35.5 g/mol so 61.7g is 1.74 mol
Then we divide each by the smallest number, 0.866 and get
0.866/0.866 = 1
0.866/0.866 = 1
1.74/0.866 = 2
Then the ratio is 1:1:2 so we have
