Answer to Question #320200 in General Chemistry for Lis

Question

A. 5% by volume, 25 ml HNO3 solution. Find mass solute

Answer 1

(Volume/Volume)%= = (Volume of solute)/(total volume of solution mL)×100

Given : 5% by volume

and total volume of solution = 25 mL

So, put given data in above

5 = (volume of solute /25mL) ×100

Volume of solute = (5 × 25)/100

=1.25 mL
