Question

How many grams of NaOH will be needed to prepare 350 mL of 0.1 M solution

Answer 1

Answer:

We know molarity is the ratio of number of moles to the volume of solution in litres.

Here, molarity is 0.1

Volume=250ml

Moles of NaOH=0.1*250/1000=1/40

Moles=Mass/Molar mass

=>Mass=1/40*40=1g
