Question

Calculate the density of an acid if 138.4 mL of the avid weighs 16.14g

Answer 1

`0.12g/cm^3`

Step-by-step explanation:

Firstly, you should use this formula :

`Density=(mass)/(volume)`

We know the mass is 16.14g, and volume as
`138.4ml`.

Also remember to convert
`ml` to
`cm^3`, where
`1ml = 1cm^3`

Therefore,
`138.4ml=138.4cm^3`.

Substitute the value :

`(16.14g)/(138.4cm^3)=0.1166g/cm^3`

Rounding it to 2 significant figure :

`0.12g/cm^3`

Hope this helped
