HOW MANY MOLES ARE THERE IN 5G OF SODIUM HYDROXIDE

rn

Given mass = 5g

Molar mass of NaOH = 40g

Moles = mass / molar mass

= 5 / 40

= 0.125 moles

So, 0.125 moles are present in 5g of NaOH.

given mass = 5g 

molecular mass of sodium hydroxide = 23 + 16 + 1 = 40g

thereforce,

no. of moles = given mass / molecular mass

= 5 / 40

= 0.125 mole
