Given that the atomic weight of hydrogen is appoximately 1 gram per mole, use the method above to estimate teh average molecular mass for water vapor

Answer : The average molecular mass of water vapor is, 18 g/mol

Explanation :

Molar mass : It is defined as the sum of the mass of all the atoms each multiplied its atomic masses that are present in the molecular formula of a compound. It is expressed in g/mol.

As we know that,

Atomic weight of hydrogen = 1 g/mole

Atomic weight of oxygen = 16 g/mole

Now we have to calculate the average molecular mass of .

Average molecular mass of =

Therefore, the average molecular mass of water vapor is, 18 g/mol

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
