Question

What is the mass of 5.07 mol N2?

(Answer)grams (3 SF)

Answer 1

Mass, m = 141.96 kg

Step-by-step 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.

`n=(m)/(M)`

Where

m is mass of 5.07 mol of N₂

So,

`m=n* M\\\\m=5.07* 28\\\\m=141.96\ kg`

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