Question

What is the volume of 67.1g of ethyl alcohol, which has a density of 0.79 g/mL?

Answer 1

`84.94\ \text{mL}`

Step-by-step explanation:

`m` = Mass of ethyl alcohol =
`67.1\ \text{g}`

`\rho` = Density of ethyl alcohol =
`0.79\ \text{g/mL}`

`V` = Volume of ethyl alcohol

Density is given by

`\rho=(m)/(V)\\\Rightarrow V=(m)/(\rho)\\\Rightarrow V=(67.1)/(0.79)\\\Rightarrow V=84.94\ \text{mL}`

The volume of ethyl alcohol is
`84.94\ \text{mL}`.
