The mass of water is 10 grams.

Explanation:

It is given that,

Density of water, $d=1\ g/cm^3$

Volume of water, $V=10\ cm^3$

We need to find the mass of the water. Let it is given by m. It can be calculated using the definition of density. Its formula is given by :

$d=\dfrac{m}{V}$

$m=d\times V$

$m=1\ g/cm^3\times 10\ cm^3$

m = 10 grams

So, the mass of water is 10 grams. Hence, this is the required solution.
