A strontium hydroxide solution is prepared by dissolving 10.50 g of Sr(OH)2 in water to make 65.00 mL of solution. What is the molarity of this solution? Express your answer to four significant figures and include the appropriate units.

The molarity of strontium hydroxide solution is 1.328 M

Explanation:

To calculate the molarity of solution, we use the equation:

Given mass of strontium hydroxide = 10.50 g

Molar mass of strontium hydroxide = 121.63 g/mol

Volume of solution = 65.00 mL

Putting values in above equation, we get:

Hence, the molarity of strontium hydroxide solution is 1.328 M

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
