Question

5moles of AB2 weight 125×10^-3kg and 10 moles of A2B2 weight 300×10^-3kg the molar mass of A and molar mass of B in kg mol^-1 are​

Answer 1

Answer:

Molar mass of A: 25 x 10^-3 kg/mol

Molar mass of B: 30 x 10^-3

Explanation:

No.of = given mass/molar mass

moles

5 = 125 x 10^-3/molar mass

Molar mass = 125 x 10^-3/5

Molar mass of A = 25 x 10^-3

Similarly molar mass of B can be found out

Answer 2

Answer:

MA+2MB=25

2MA+2MB=30

from

MA=5

MB =10
