Question

An unknown liquid has a mass of 4.25 × 108 mg and a volume of 0.250 m3. what is the density of the liquid in units of g/ml?

Answer 1

Density of the liquid in units of g/ml is
`1.836 * 10^(-6) g / \mathrm{ml}`

Step-by-step explanation:

Density of liquid is the mass of the liquid ids divided by its volume.

Density =
`\frac{\text { Mass }}{\text { Volume }}`

Given Mass = 4.25×108 mg

= 459mg

= 0.459g

Volume =
`0.250 m^(3)`

Therefore, density =
`(0.459)/(0.250)`

=
`1.836 \mathrm{g} / \mathrm{m}^(3)`

converting to
`m^(3)` to ml (
`m^(3)` = 1000000ml)

=
`1.836 * 10^(-6) g / \mathrm{ml}`

Answer 2

density= mass/volume
step one :
convert m3 to ml
1m^3 =1000000ml
0.250m^3 x1000000=250000ml

step two: convert mg to g
1mg=0.001g, therefore 4.25 x108mg=0.459g
density is therefore= 0.459g/250000=1.836 x10^-6g/ml
