Question

I need help with the sample volume problem it’s the first one

Answer 1

1) Volume of the sample.

List known and unknown values

Density: 0.768 g/mL

Mass: 23.9 g

Volume:

2) Set the equation

`\rho=(m)/(v)`

ρ: Density

m: mass

v: volume

Plug in the known values and solve for v.

`0.768(g)/(mL)=\frac{23.9\text{ g}}{v}`
`v=\frac{23.9\text{ g}}{0.768(g)/(mL)}=31.1mL`

The volume of the sample is 31.1mL.
