Respuesta :

Molar mass of NaNO3 is 84.9947 g/mol

Moles=given mass/molar mass

So, 44g/84.9947 g/mol=0.52mol.

Answer : The number of moles of [tex]NaNO_3[/tex] present in a given sample are 0.518 moles.

Explanation : Given,

Mass of [tex]NaNO_3[/tex] = 44.0 g

Molar mass of [tex]NaNO_3[/tex] = 84.99 g

Formula used :

[tex]\text{Moles of }NaNO_3=\frac{\text{Mass of }NaNO_3}{\text{Molar mass of }NaNO_3}[/tex]

Now put all the given values in this formula, we get:

[tex]\text{Moles of }NaNO_3=\frac{44.0g}{84.99g.mol}=0.518mole[/tex]

Therefore, the number of moles of [tex]NaNO_3[/tex] present in a given sample are 0.518 moles.
