Question

What is molarity of NaOH in the Solution, that is prepared by adding 2 gram NaOH in water to get 500 mL of the solution

Answer 1

Answer:

Molarity is 0.1M of NaOH solution

Explanation:

No of moles of NaOH = mass/mol.mass

= 2/40 = 1/20= 0.05moles

Molarity = no of moles / volume in litres

0.05. / 0.5 litre

........ = 5/ 50

1/10

. = 0.1 mol/lite (M)

Hope this helps you...

Answer 2

No of moles of NaOH = mass/mol.mass

2/40 = 1/20= 0.05moles

Molarity = no of moles / volume in litres

0.05. /0.5 litre

= 5/ 50

1/10

= 0.1 mol/lite (M)
