Platinum has a density of 21 g/cm3. a platinum ring is placed in a graduated cylinder that contains water. the water level rises from 5.0 ml to 5.3 ml when the ring is added. what is the mass of the ring?

The mass of the ring is 6.3 kg.

Explanation:

It is given that,

Density of platinum,

A platinum ring is placed in a graduated cylinder that contains water. the water level rises from 5.0 ml to 5.3 ml when the ring is added. the volume of the ring is, (5.3 - 5) mL = 0.3 mL

Volume of the ring,

We need to find the mass of the ring. The density of any substance is given by :

m = 6.3 kg

So, the mass of the ring is 6.3 kg. Hence, this is the required solution.

d) physical means can be used to separate the components of air.
