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

n = 1.7 moles

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

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