What is the mass of ethyl alcohol that fills a 250.0-mL graduated cylinder? The density of ethyl alcohol is 0.789 g/mL.

Explanation:

The density formula is:

Rearrange the formula for m, the mass. Multiply both sides of the equation by v.

Mass can be found by multiplying the density and volume. The density of ethyl alcohol is 0.789 grams per milliliter. The alcohol fills a 250 milliliter graduated cylinder, so the volume is 250 milliliters.

Substitute the values into the formula.

Multiply. Note that the milliliters, or mL will cancel each other out.

The mass of the ethyl alcohol is 197.25 grams.
