For each of the following solutions, the mass of solute taken is indicated, along with the total volume of solution prepared. Calculate the normality of each solution.
(a) 0.139 g NaOH; 10.5 mL
(b) 11.5 mg Ca(OH)2; 100. mL
(c) 12.5 g H2SO4; 195 mL
(a) The moles of 0.139 g of NaOH is: 0.139 / 40 = 0.003475 mol
the molarity of the solution is c = 0.003475 / 0.0105 = 0.33 M.
1 mol of NaOH can ...
It shows how to calculate the normality. The solution was rated '5/5' by the student who originally posted the questions.
