Question

quantos átomos corresponde a 4 mol de átomo de nitrogênio ?​

Answer 1

$\boxed{\begin{array}{l}\sf 2~mols~de~\acute atomos\longrightarrow 2\cdot6,02\cdot10^{23}\acute atomos\\\sf 4~mols~de~\acute atomos\longrightarrow x\\\sf 2x=8\cdot6,02\cdot10^{23}\\\sf x=\dfrac{8\cdot6,02\cdot10^{23}}{2}\\\sf x=4\cdot6,02\cdot 10^{23}\\\sf x=24,08\cdot10^{23}\\\sf x=2,408\cdot 10^{24}\acute atomos\end{array}}$
