I also want this answer. if you will get this please send me.

Answer 2

Answer:

ans : 24g/mol

Explanation:

No of mole =

$\frac{5 \times {10}^{22} }{6 \times {10}^{23} } = \frac{1}{12} mol$

Molecular mass= Mass÷Mole

so Molecular mole=

$\frac{2g}{ \frac{1}{12}mol } = 2 \times 12 = 24g {mol}^{ - 1}$
