(Enter just the number for this one.)

Answer 1

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}=(135g)/(23g/mole)=5.869moles`

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