Question

calculate number of atoms of 100g of N2

Answer 1

$moles = \frac{given \: mass}{molar \: mass} \\ or \\ moles = \frac{no. \: of \: atoms}{avogadro \: no.} \\ \frac{given \: mass}{molar \: mass} = \frac{no. \: of \: atoms}{avogadro \: no.} \\ \frac{100}{25} = \frac{no. \: of \: toms}{6.022 \times {10}^{23} } \\ no. \: of \: atoms = \frac{6.022 \times {10}^{25} }{28} \\ no. \: of \: atoms \: will \: be \\ 0.215 \times {10}^{25} \\ 2.15 \times {10}^{24}$
