Question

number of moles present in 56g of nitogen atoms

Answer 1

Atomic mass of nitrogen = 14 g

So, 14 g of atomic nitrogen represents 1 mole of atomic nitrogen.

Molar mass of atomic nitrogen = 14 g/mol.

According to formula,

Number of moles = $\frac{given \:mass}{molar \: mass}$

Number of moles = 56/14

Or, Number of moles = 4

So, 4 moles of nitrogen.

Answer 2

Answer:

Explanation:

We know that number of moles of a particular substance is defined as the ratio of its given mass to the molar mass.Molar mass of nitrogen ($N_{2}$) =28g$\textbf{Number of moles}$ = $\frac{Given \: mass}{Molar \: mass}$$\text{So,answer is \frac{56}{28} =2}$$\fbox{\textbf{The \: number \: of \: moles \: of \: 56g\: nitrogen \: atoms \: is \: two}}$
