This Atomic weight is the weight of 1 mole of atoms of that kind. For instance look at N (Nitrogen), you will see the atomic mass is 14.00674 grams. So that means if you had 1 mole of nitrogen atoms, it would weight, 14.00674 grams.

◾◾here is your answer...

Approach to solving Question;- 1st we find mass of 1 mole ( it is standard value) . Than multiply this by given no. Of moles.

(a) The mass of 1 mole of nitrogen atoms is 14g.

(b) The mass of 4 moles of Al

=4 × 27 g

= 108g

(c) The mass of 10 moles of Na2SO3

=10 × [2 × 23 + 32 + 3 × 16]g

= 10 × 126g

= 1260g

I hope, this will help you.

Thank you______❤
