you have a lead ball with a mass of 420 g. the density of lead is 10.5 g/cm³. what is the volume of the ball

The answer is

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

From the question

mass = 420 g

density = 10.5 g/cm³

The volume is

We have the final answer as

Hope this helps you

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

explanation:

0.07 g/cm³

1.37 g/cm³
