Question

Ethanol is a biofuel that can be produced from corn starch similar to the way whiskey is made. Regular gasoline is 10% ethanol. The density of ethanol is 0.789 g/mL. What is the volume of a sample of ethanol that has a mass of 500.0 grams?

a) 632.91 mL
b) 394.52 mL
c) 634 mL
d) 400.63 mL

Answer 1

To calculate the volume of a sample of ethanol with a given mass, divide the mass by the density of ethanol. The volume of a sample with a mass of 500.0 grams is approximately 632.91 mL.

Step-by-step explanation:

To calculate the volume of a sample of ethanol with a given mass, we can use the equation:

Volume = Mass / Density

Given that the mass of the ethanol sample is 500.0 grams and the density of ethanol is 0.789 g/mL, we can substitute these values into the equation:

Volume = 500.0 grams / 0.789 g/mL = 632.91 mL

Therefore, the volume of the ethanol sample is approximately 632.91 mL.
