Question

Calculate the number of moles in 14g of nitrogen gas?​

Answer 1

Answer:

14 grams is the molar mass of nitrogen meaning that one mole of nitrogen atoms is 14 grams. One mole of any substance has 6.02*10^23 atoms/molecules of that subtance therefore there are 6.02*10^23 atoms of nitrogen in 14g of nitrogen.

Explanation:

Answer 2

Given: 14 grams of nitrogen gas.

To find: We have to find the number of moles.

Solution:

To calculate the number of moles we have to follow the below steps-

Nitrogen has an atomic mass of 14 grams.

Thus nitrogen gas will contain a molecular mass of 14×2=28 grams.

Now we know that 28 grams of nitrogen gas have 1 mole.

So, 14 grams of nitrogen gas will contain 14/28=0.5 moles.

14 grams of nitrogen gas has 0.5 moles.
