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 :
[tex]\text{Moles of sodium}=\frac{\text{Mass of sodium}}{\text{Molar mass of sodium}}[/tex]
Now put all the given values in this formula, we get
[tex]\text{Moles of sodium}=\frac{135g}{23g/mole}=5.869moles[/tex]
Therefore, the moles of sodium present in 135 grams of sodium is, 5.869 moles.
