Question 1

Question 2

B. Percent by volume

Question 1

The formula for percent by volume is

If your solution contains 50 mL of rubbing alcohol and 200 mL of water, the volume of solution is 250 mL,

Question 2

If you have 300 mL of a solution that is 2 % v/v H₂O₂,

the answer is learned

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
