Question

11. If xg of A (atomic mass 50) contains n atom how many atoms are there in 20x g of eleme B (atomic weight 100) ama b) 10 n c) 20 n d) n/10​

Answer 1

Answer:

Number of moles of B in 20x = 20 x / 100= x/5. From eq 1, n * 10 will give eq 2. Hence, answer is 10 n.

Explanation:

Number of moles of B in 20x = 20 x / 100= x/5. From eq 1, n * 10 will give eq 2. Hence, answer is 10 n.
