Respuesta :
1 mol has 6,02 * 10^23 molecules.
There are (7,50 * 10^24)/(6,02 * 10^23) = 12,458 moles.
Molar mass 454/12,458 = 36,44 g/mol.
There are (7,50 * 10^24)/(6,02 * 10^23) = 12,458 moles.
Molar mass 454/12,458 = 36,44 g/mol.
The molar mass of the substance will be "36.5 g/mol".
According to the question,
- Number of molecules = [tex]7.50\times 10^{24}[/tex]
- Mass = 454 g
Now,
→ [tex]Mass \ of \ 1 \ molecule = \frac{454}{(7.50\times 10^{24})}[/tex]
hence,
The molar mass will be:
= [tex]\frac{454\times (6.022\times 10^{23})}{7.50\times 10^{24}}[/tex]
= [tex]36.5 \ g[/tex]
Thus the solution above is right.
