Calculate the density of 93.9 g of an isopropyl alcohol-water mixture (commercial rubbing alcohol) that has a volume of 98.6 mL. Round your answer to 3 significant figures.

Answer 1

To calculate the density, we use the formula:

Density = mass / volume

First, convert the volume from milliliters to liters:
98.6 mL = 98.6 * 10^-3 L = 0.0986 L

Now, plug in the values:

Density = 93.9 g / 0.0986 L
Density = 952.93 g/L

Rounded to 3 significant figures, the density of the isopropyl alcohol-water mixture is 953 g/L.
