Question

What mass of $S{O}_2$ can be removed using $1.4\times {10}^3$ kg CaO?

• A. $1.4\times {10}^3$ kg
• B. $1.6\times {10}^3$ kg
• C. $2.2\times {10}^3$ kg
• D. $2.4\times {10}^3$ kg

Answer 1

The correct option is B $1.6\times {10}^3$ kg

Reaction:
$CaO+S{O}_2\to CaS{O}_3$
1 mole 1 mole 56gm 64gm
So, $1.4\times {10}^{3}gmCaO=\frac{64\times 1.4\times {10}^3}{56}=1.6\times {10}^3$ kg $S{O}_2$.
