JEE Main 2021 (Online) 17th March Evening Shift Chemistry - Some Basic Concepts of Chemistry Question 132 English Explanation

Stoichiometric moles of amide = 10 −- 3 mol

Actual weight of amide = 10-3 ×\times 273 = 0.273 g

% yield = 0.2100.273×100{{0.210} \over {0.273}} \times 100

= 76.9%

≃\simeq 77%
