Explanation:

Mass number of an atom means the sum of total number of protons and neutrons present in an atom.

On the other hand, atomic number is the total number of protons present in an atom.

Therefore, mass number of phosphorous is 30 g/mol whereas atomic number of phosphorous is 15 g/mol.

Thus, the mass of 1 mole of phosphorus atoms is 30 grams.

What is the characteristic of the polar water molecule?

NikAS [45]

A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons.
