PLEASE FILL IN THE TABLES BELOW. THANK YOU!

Mass of active ingredient of the ascorbic acid tablet = 1000 mg
Amount of solute used = 1000 mg = 1.0 g
Assigned concentration of stock solution = 0.8 M

= 7.1 mL
%3D
1000 mg of solute should be added to 7.1 mL water to get 0.8 M stock solution of ascorbic acid.
