question 1

Answer 1

Ans) 1. For Run 1,

            Given Volume of NaOH used = 18.25 mL

            Also, Concentration of given NaOH = 0.1 M

            $\because Concentration=\frac{No.\, of\, moles}{Volume}$

            $\therefore No.\, of\, moles=(Volume*Concentration)$

            $\Rightarrow No.\, of\, moles=(18.25\, mL)*(0.1 M)$

                                            

            Similarly, For Run 2,

            

                                        

            For Run 3,
