JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry
How many grams of residue is obtained by heating \(2.76\) g of silver carbonate?
(Given: Molar mass of C, O and Ag are \(12\), \(16\) and \(108\) g mol\(^{-1}\) respectively)
- A \(1.08\) g
- B \(2.16\) g
- C \(3.24\) g
- D \(4.32\) g
Answer & Solution
Correct Answer
(B) \(2.16\) g
Step-by-step Solution
Detailed explanation
Molar mass of \(Ag_2CO_3\) = \(2 \times 108 + 12 + 3 \times 16 = 276\) g mol\(^{-1}\) Number of moles of \(Ag_2CO_3\) = \(\dfrac{2.76}{276} = 0.01\) mol The decomposition reaction of silver carbonate on heating is:…
