What is the mass (in grams) of 500 mL of ethanol? (density of ethanol = 0.789 g/mL)

A.

394.5 mL

B.

500 mL

C.

394.5 g

D.

500 g

Correct answer is C

To calculate the mass of a substance, we can use the formula:
Mass = Volume x Density
Given the volume of ethanol is 500 mL and the density of ethanol is 0.789 g/mL, we can plug the values into the formula:
Mass = 500 mL x 0.789 g/mL = 394.5 g
