The density of a pure substance is its mass per unit volume. The density of hexane has been measured to be 655. g/L. Calculate the mass of 555. mL of hexane. Be sure your answer has a unit symbol and the correct number of significant.

The mass of hexane is 364 grams

Explanation:

Step 1: Data

Density = 655 g/L

Volume = 555 mL

Step 2 Convert the volume from mL to L

555 mL = 555 * 10^-3 L = 0.555 L

Step 3: Calculate mass

Density = mass hexane / volume

Mass hexane = density * volume

Mass hexane = 655 g/L * 0.555 L

Mass hexane = 364 grams

The mass of hexane is 364 grams
