32. Question #16
Compute for the percent by volume
of 13mL of alcohol in 57mL of water.
Time starts now...
910876543210

33. ANSWER
Solution:
Volume of solution = 13 mL + 57mL
= 70mL
%volume = (13mL/70mL) x 100
= 18.57%

34. Question #17
What is the percent by mass of 6.2g
of alum dissolved in a 412.7mL of
water? (Note: 1mL = 1g)
Time starts now...
910876543210

35. ANSWER
Solution:
Conversion: 412.7mL = 412.7g
Mass of solution = 6.2g + 412.7g
= 418.9
%mass = (6.2g/418.9g) x 100
= 1.48%
