Question

Cat cantareste o molecula de hidrogen H2 .Am nevoie urgent .Imi aratati cum ati facut calculul.Dau coroana

Answer 1

$\diplaystyle\mathtt{M_{H_2}=2A_H=2g/mol} \\ \\ \mathtt{1 \ mol \ H_2=6,023\cdot 10^{23} \ molecule} \\ \\ \mathtt{\text{Masa unei molecule este:}} \\ \\ \mathtt{\frac{2}{6,023\cdot 10^{23}}\approx 3,32*10^{-24}g}$
