Question

calculate the molarity of a solution containing 8 gram of NaOH in 500 ml of water​

Answer 1

Answer:

0.4 Molar

Step-by-step explanation:

Molarity = Moles of solute / Litres of solution

8gm NaOH = 8/40 moles = 1/5 moles

500ml = 1/2 litre

therefore,

Molarity = (1/5)/(1/2)

=2/5

= 0.4 Molar

Hope this helps.
