Answer : 135 grams of sodium has 5.869 moles.

Solution : Given,

Mass of sodium = 135 grams

Molar mass of sodium = 23 g/mole

Formula used :

$\text{Moles of sodium}=\frac{\text{Mass of sodium}}{\text{Molar mass of sodium}}$

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

$\text{Moles of sodium}=\frac{135g}{23g/mole}=5.869moles$

Therefore, the moles of sodium present in 135 grams of sodium is, 5.869 moles.
