Question

If there is 60cm3 of oil in ameasuing cylinder.what will be its mass

Answer 1

Answer: 0.057 kg

Step-by-step explanation:

We can find the mass of the oil if we know its density and the volume it occupies. Since the density
`\rho` is a relation between the mass
`m` and the volume
`V` of a substance:

`\rho=(m)/(V)` (1)

Now, the density of oil is generally between
`700 (kg)/(m^(3))` and
`950 (kg)/(m^(3))`. However, in this case we will take
`950 (kg)/(m^(3))` as its density.

In adition, we are given as data the volume thw oil occupies:

`V=60 cm^(3) (1 m^(3))/((100 cm)^(3))=6(10)^(-5) m^(3)`

Writing these values in (1):

`950 (kg)/(m^(3))=(m)/(6(10)^(-5) m^(3))` (2)

Isolating
`m`:

`m=0.057 kg` This is the mass of the oil
