D=m/V=0.72/0.1x0.08x0.02=4500(kg/m3)
Answer:
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
![n=\dfrac{23.8}{14}\\\\n=1.7](https://tex.z-dn.net/?f=n%3D%5Cdfrac%7B23.8%7D%7B14%7D%5C%5C%5C%5Cn%3D1.7)
So, there are 1.7 moles in 23.8 grams of Nitrogen.
