Question

${CO}_2$ contains $27.27$% of carbon, ${CS}_2$ contains $15.79$% of carbond, ${SO}_2$ contains $50$% sulphur. What will be the ratio of $S:O$ in ${SO}_2$?

• A. $1:1$
• B. $1:2$
• C. $2:1$
• D. $3:2$

Answer 1

The correct option is A $1:1$

Consider $S{O}_2$ ,
% of sulphur= 50
% of oxygen=100-50=50
50g of sulphur combines with 50g of oxygen.
The ratio of the mass of sulphur to that of oxygen is 50:50 that is 1:1
conclusion: hence the option (A) is correct.
