Question

Calculate the number of moles in 23.8 grams of Nitrogen, N.

Group of answer choices

a 1.70

b 1.43x10^25

c 333

d 3.95x10^-23

Answer 1

n = 1.7 moles

Step-by-step explanation:

Given mass, m = 23.8 grams

Molar mass of Nitrogen = 14 g/mol

Let there is n number of moles. We know that,

No. of moles = given mass/ molar mass

`n=(23.8)/(14)\\\\n=1.7`

So, there are 1.7 moles in 23.8 grams of Nitrogen.
