Answer 1

Step-by-step explanation:

It is known that number of moles of a substance equal to mass divided by its molar mass.

Mathematically, No. of moles =
`\frac{mass}{\text{molar mass}}`

It is given that no. of oles present are 27.2 mol and molar mass of N is 14 g/mol.

Therefore, calculate mass of N as follows.

No. of moles =
`\frac{mass}{\text{molar mass}}`

27.2 mol =
`(mass)/(14 g/mol)`

mass = 380.8 g

Thus, we can conclude that mass of N is 380.8 g.
