Question

Find the mass of 2 moles of nitrogen atoms.

Answer 1

Given moles on N atom = 2 moles

Gram atomic mass of nitrogen atoms = 14g

Therefore, 14g of nitrogen atoms = 1 mole of nitrogen atoms

So, 2 moles of nitrogen atoms = 14 × 2g of nitrogen atoms

Hence, 2 moles of nitrogen atoms weigh 28g.
