What is the percent by volume of isopropyl alcohol in a solution that contains 45 ml of isopropyl alcohol in 1.4 L of water?
1 answer:
Hey there!
There are 1000 mL in a liter.
1.4 L + 0.045 L = 1.445 L
In total there is 1.445 L of the solution.
To find the percent of isopropyl alcohol, divide the amount of isopropyl alcohol by the total amount.
0.045 ÷ 1.445 = 0.0311
Convert to a percent.
3.11%
