Question

The total number of gram molecules of $S{O}_{2}C{l}_2$ in $13.5$ g of sulphuryl chloride is:

• A. 0.1
• B. 0.2
• C. 0.3
• D. 0.4

Answer 1

The correct option is A 0.1

The molar mass of sulphuryl chloride is $32+16+16+35.5+35.5=135g/mol$

The number of gram molecules in 13.5 g of sulphuryl chloride is $\frac{13.5}{135}=0.1mol$.
