Question

If the weight of 0.125 moles of a compound is 0.125 g then what would be its molecular weight ?

Answer 1

Hello Mate!

What is molecular weight?

When elements of periodic table combine then their element masses also get added up. For example : H2O = [( 1 × 2 ) + ( 16 × 1 )]u

Hence molecular mass of H2O is 18 g/mol.

1 mole of some compound = x g

0.125 mole of some compound = 0.125 × x g

Since we know that weight of 0.125 mole of sone compound is 0.125 g.

0.125 g = 0.125 × x g

1 g = x

Molecular weight of some compound is 1 gram.

Have great future ahead!
