Answer:
Explanation:
To calculate the "weight" (mass) of ethyl alcohol, we have to use this formula:
 Density will have units of

The mass has units of grams,
#g# . 
The volume will have units of
#mL# or#cm^3#
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:
Thus, ethyl alcohol weighs 158g.
