3) What is the weight of the ethyl alcohol that exactly fills a 200.0 mL container? The density of ethyl alcohol is 0.789
g/mL.

158g

Explanation:

To calculate the "weight" (mass) of ethyl alcohol, we have to use this formula:

- Density will have units of gmL when dealing with a liquid or units of gcm3 when dealing with a solid.

The mass has units of grams, g.

The volume will have units of mL or cm3

We are given the density and volume, both of which have good units so all we have to do is rearrange the equation to solve for the mass:

density×volume=massvolume×volume

Density×Volume = Mass

0.789gmL×200.0mL

Thus, ethyl alcohol weighs 158g.
