Question

Determine the mass of 6.022×10^23 no.of N2 molecules. ​

Answer 1

Explanation:

no.of moles = given mass / molar mass

no.of moles = 1 mol

N2 molar mass = 2*14=28

1=x/28

x=28 gram

Answer 2

Answer:

The mass of 6.022 × $10^{23}$ molecules of $N_{2}$ is 28 g.

Explanation:

We know that one mole of the compound contains an Avogadro number of particles.

That is 6.022 × $10^{23}$ molecules implies one mole

Here 6.022 × $10^{23}$ molecules of $N_{2}$ ⇒ 1 mole of $N_{2}$

Therefore, Mass = Number of moles × molar mass

we know that the molar mass of $N_{2}$ = 28 g/mol

That is, Mass = 1 × 28 = 28 g
