Question

A2 +B -> A2B

If A atomic mass is 10 and B atomic mass is 5
Given , 3×10^21 molecules of A2 and 6 ×10^23 molecules of B..
Find the mass of product formed ??

Answer 1

Answer:

Let x and y be atomic masses of A and B respectively

0.15=

x+2y

9.3

and 0.15 =

2x+3y

15.9

x+2y=62 and 2x +3y=106

y=18 and x=26

Answer 2

Explanation:

atomic mass of the product A2B=25
