Question

Given that density of water is 1 g $ml^{-1}$. What is its density in kg $m^{-3}$?

Answer 1

Given from the question, density of water is 1g/ml.

To calculate the its density in $Kgm^{-3}$

We know that density of any matter = mass/volume

We also know that,

1Kg = 1000g; and $m^{3}$ = 1000L

Substituting the values, then

Density = 1000g/1000ml = 1g/L

We know that L = 1000ml or $10^{3}$ml

So, Density = 1000g/1000ml = 1g/ml

We know that the density varies with temperature. It is not absolute all the time.
