Question

a chemist combines water and isopropanol to make a mixture with a volume of 38 milliliters (ml). the volume of isopropanol in the mixture is 10 ml. what is the volume of water, in ml, in the mixture? (assume that the volume of the mixture is the sum of the volumes of water and isopropanol before they were mixed.) enter your numerical answer. enter your answer... enter your answer as a number, fraction, or decimal

Explanation:

Step1: Identify the total - volume formula

The total volume of the mixture $V_{total}=V_{water}+V_{isopropanol}$.

Step2: Rearrange the formula to solve for $V_{water}$

$V_{water}=V_{total}-V_{isopropanol}$.

Step3: Substitute the given values

Given $V_{total} = 38$ mL and $V_{isopropanol}=10$ mL. Then $V_{water}=38 - 10$.

Step4: Calculate the result

$V_{water}=28$ mL.

Answer:

28
