Answer 2

◆Asked◆

Calculate mass of one atom of nitrogen in gram.

◆Solution◆

The molar mass of Nitrogen = $14g/mole$

∴ Mass of 1 mole of Nitrogen = 14 g

1 mole contains $6.022 \times 10 ^{23}$ atoms.

∴ Mass of $6.022 \times 10 ^{23}$ atoms of Nitrogen = 14g.

Mass of 1 atom of Nitrogen = $\frac{14}{6.022 \times 10 ^{23 \: atoms} }$

∴ Mass of 1 atom of Nitrogen is:- $2.32 \times 10 ^{ - 23} g$

In chemistry, the molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured in moles. The molar mass is a bulk, not molecular, property of a substance.

Formula:-

$M = m/n$

Here,

M = molar mass

m = mass of a substance (in grams)

n = number of moles of a substance
