Question

A solution of Ca(OH)2 is prepared by dissolving 5.2mg of Ca(OH)2 to a total volume of 1000 cm3. Calculate the molarity of the solution.
​

Answer 1

Answer:

Hey sistah, here's your answer:-

Given mass = 5.2mg

Molar mass = 74 g

Volume = 1000ml = 1000cm^3

Molarity = no. of moles / 1000 ml

1 l = 1000ml

Hence, molarity = 0.07 M
