<u>Answer:</u> The molarity of LiOH is 0.139 M
<u>Explanation:</u>
To calculate the number of moles for given molarity, we use the equation:
.....(1)
Molarity of iron (II) chloride solution = 0.210 M
Volume of solution = 11.6 mL = 0.0116 L (Conversion factor: 1 L = 1000 mL)
Putting values in equation 1, we get:
For the given chemical reaction:
By Stoichiometry of the reaction:
1 mole of iron (II) chloride reacts with 2 moles of LiOH
So, moles of iron (II) chloride will react with = of LiOH
Calculating the molarity of LiOH by using equation 1:
Moles of LiOH =
Volume of LiOH = 35.1 mL = 0.0351 L
Putting values in equation 1, we get:
Hence, the molarity of LiOH is 0.139 M
