Final answer:
To calculate the volume of 80.0 g of ether with a density of 0.70 g/mL, you divide the mass by the density resulting in a volume of 114.29 mL.
Step-by-step explanation:
To find the volume of 80.0 g of ether, given the density of ether is 0.70 g/mL, you use the formula for density which is:
Density = Mass / Volume
By rearranging the formula to solve for volume, you get:
Volume = Mass / Density
So, you divide the mass of the ether by its density:
Volume =

The volume of 80.0 g of ether is therefore 114.29 mL. It's important to note that when performing calculations involving density, mass, and volume, it's crucial to ensure that all measurements are in compatible units.
