Convert 6.71 moles NH3 to number of molecules.
svetlana [45]

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}.
