Question

Convert 2 moles of magnesium sulphate sample into number of molecules present in the sample

Answer 1

By the Law of Avogrado we understand that 1 mol of a substance is equivalent to 6.02x10²³ molecules, therefore:

1 mol → 6.02*10²³ molecules
2 mol → y

$\frac{1}{2} = \frac{6.02*10^{23}}{y}$
Product of extremes equals product of means:
$1*y = 2*6.02*10^{23}$
$y = 12.04*10^{23}$
$\boxed{\boxed{y \approx1.2*10^{24}\:molecules\:of\:magnesium\:sulphate}}\end{array}}\qquad\quad\checkmark$

Answer 2

No : of particles (molecules) = No: of moles × Avogadro no:
= 2 × 6.022 × 10²³
= 12.044 × 10 ²³ molecules.
