Question

Convert 6.71 moles NH3 to number of molecules.

Answer 1

Answer: There are $40.41 \times 10^{23}$ molecules present in 6.71 moles of $NH_{3}$.

Explanation:

Given: Moles of $NH_{3}$ = 6.71 mol

According to the mole concept, 1 mole of every substance contains $6.022 \times 10^{22}$ molecules.

Therefore, molecules present in 6.71 moles are calculated as follows.

$Molecules = moles \times 6.022 \times 10^{23}\\= 6.71 \times 6.022 \times 10^{23}\\= 40.41 \times 10^{23}$

Thus, we can conclude that there are $40.41 \times 10^{23}$ molecules present in 6.71 moles of $NH_{3}$.
