Expert Solution

Step 1

Since you have posted a question with multiple sub-parts, we will solve first three subparts for you. To get remaining sub-part solved please repost the complete question and mention the sub-parts to be solved.

Step 2

Given:

Volume of HBr = 75.00 mL

Molarity of HBr = 0.310 M

Volume of Ca(OH)₂ = 93.00 mL

Concentration of Ca(OH)₂ = 0.250 M

The reactant which is present in lesser amount and get totally consumed in the reaction is termed as limiting reactant or limiting reagent.

Step 3

Calculating moles of HBr and Ca(OH)₂:

$\begin{array}{rcl} M o l e s o f H B r & = & M o l a r i t y \times V o l u m e \\ = & 0.310 m o l / L \times 75.00 m L \times \frac{1 L}{1000 m L} \\ = & 0.02325 m o l \\ M o l e s o f C a {(O H)}_{2} & = & M o l a r i t y \times V o l u m e \\ = & 0.250 m o l / L \times 93.00 m L \times \frac{1 L}{1000 m L} \\ = & 0.02325 m o l \end{array}$
