Question

a chemist combines water and isopropanol to make a mixture with a volume of 36 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.)

Explanation:

Step1: Identify the relationship

The volume of the mixture is the sum of the volumes of water and isopropanol. Let the volume of water be \(x\) mL. Then \(x + 10=36\).

Step2: Solve for \(x\)

Subtract 10 from both sides of the equation: \(x=36 - 10\).

Answer:

26
