QNEET-2023-Ch-213: NEET 2023 Chemistry - Class 11 NEET-2023-Ch-213 Solution: The right option for the mass of \(CO_2\) produced by heating…
The right option for the mass of produced by heating 20 g of 20% pure limestone is (Atomic mass of Ca=40) [] 1.76 g 2.64 g 1.32 g 1.12 g
Multiple Choice Options
- A 1.76 g
- B 2.64 g
- C 1.32 g
- D 1.12 g
Step-by-Step Verified Solution
Weight of impure limestone = 20 g
Weight of pure limestone ( CaCO 3 ) = 20 % of 20 g
= 20 100 _ 20
= 4 g
n CaCO 3 = 4 100 = 0.04
Image
n CO 2 = 0.04
W CO 2 = 0.04 _ 44
= 1.76 g
