What is the density of a 9.0 gram object that displaces 13 cm3 of water?

Density of a substance can be defined as the mass of that substance per unit volume.

Given the mass of object = 9.0 g

Volume of the object will be the volume of water displaced by the object

So, volume of the object =

Calculating the density from mass and volume:

= 0.69

Therefore, the density of given object is 0.69

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²
