<u>Answer:</u> The molar mass of is 208.88 g/mol
<u>Explanation:</u>
To calculate the number of moles for given molarity, we use the equation:
Molarity of NaOH solution = 0.500 M
Volume of solution = 45.0 mL = 0.045 L (Conversion factor: 1 L = 1000 mL)
Putting values in above equation, we get:
The chemical equation for the reaction of NaOH and follows:
By Stoichiometry of the reaction:
2 moles of NaOH reacts with 1 mole of
So, 0.0225 moles of NaOH will react with = of
To calculate the number of moles, we use the equation:
Given mass of = 2.35 g
Moles of = 0.01125 moles
Putting values in above equation, we get:
Hence, the molar mass of is 208.88 g/mol
