In a compound, elements A and B have a mass ratio of 2:3. If the mass of A is 4 g, what is the mass of B?किसी यौगिक में तत्व A और B का द्रव्यमान अनुपात 2:3 है। यदि A का द्रव्यमान 4 g है, तो B का द्रव्यमान कितना होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 6 g6 g
In the 2:3 ratio, 2 parts correspond to 4 g, so 1 part is 2 g. Thus, B has a mass of 3 × 2 g = 6 g.2:3 अनुपात में 2 भाग 4 g के बराबर हैं, इसलिए 1 भाग 2 g होगा। अतः B का द्रव्यमान 3 × 2 g = 6 g है।
