Question

Calculate the no.of atoms in 3 mol of nh3

Answer 1

I think firstly u should multiply 3*6.022*10^23 which is Avogadro's no then multiply it by 4 as NH3 has one N and 3H atoms

Answer 2

Mole is the SI unit of expressing the amount of substance.

Given:

• The moles of $NH_{3}$ = 3

To find:

• The number of molecules in 3 moles of $NH_{3}$

Formula used:

• $Number of moles = \frac{Number of molecules}{Avogadro Number}$

Explanation:

• Number of moles = No. of molecules/Avogadro number
• No. of molecules = 3$N_{A}$
• No. of molecules = $3 * 6.022 * 10^{23}$ = $18.066 * 10^{23}$

There will be $18.066 * 10^{23}$ a number of molecules present in 3 moles $NH_{3}$.
