| (Atomic mass \[Ca:40,\text{ }C:12,O:16\]) |
A) 0.224
B) 2.24
C) 22.4
D) 224
Correct Answer: B
Solution :
[b] \[\underset{1mol}{\mathop{\underset{1mol}{\mathop{CaC{{O}_{3}}}}\,}}\,+{{H}_{2}}S{{O}_{4}}\to \underset{10g}{\mathop{\underset{100g}{\mathop{CaS{{O}_{4}}}}\,}}\,+\underset{2.24\,litre}{\mathop{\underset{22.4\,litre}{\mathop{{{H}_{2}}O}}\,}}\,+C{{O}_{2}}\]
