The number of moles, n

$= \: \dfrac{given \: number \: of \: particle}{Avogadro \: number} \: = \: \dfrac{n}{n_0} \\ \\ \\ = \: \dfrac{3.011 \times 10 {}^{23} }{6.022 \times 10 {}^{23} } \\ \\ \\ ⇏ m \: = \: M \: \times \: n\: = \: 14 \times \frac{ 3.011 \times 10 {}^{23} }{6.022 \times 10 {}^{23} } \\ \\ \\ = \: 14 \times 0.5 = 7g$
