A solution of rubbing alcohol is 75.7 % (v/v) isopropanol in water. How many milliliters of isopropanol are in a 87.7 mL sample
beks73 [17]

Answer:

66.4 mL

Explanation:

A 75.7% (v/v) value, means that f<u>or every 100 mL of rubbing alcohol, there are 75.7 mL of isopropanol.</u>

With the above information in mind, we can s<u>olve the problem by multiplying 87.7 mL by 75.7 %</u>:

87.7 mL * 75.7 / 100 = 66.4 mL

So there are 66.4 mL of isopropanol in 88.7 mL of rubbing alcohol.
