Answer:

Mass, m = 141.96 kg

Explanation:

Given that,

Moles = 5.07

Molar mass of N₂ = 28 g/mol

We need to find the mass of 5.07 mol N₂.

We know that,

No of moles is equal to mass divided by molar mass i.e.

[tex]n=\dfrac{m}{M}[/tex]

Where

m is mass of 5.07 mol of N₂

So,

[tex]m=n\times M\\\\m=5.07\times 28\\\\m=141.96\ kg[/tex]

So, the required mass of 5.07 mol N₂ is 141.96 kg.
