Determine the molecular weight of H20.<br> o 18 g<br> O 18.0 g<br> O 18.01 g<br> O 18.016 g
Sonbull [250]

Answer:

The correct answer is D

<u>18.016 g</u>

<u></u>

Explanation:

Molecular Weight : It is the sum of atomic weights of each atoms present in the compound.

The molecular weught is measured in atomic mass.unit( amu) or simply"u"

This is calculated by using :

Molecular weight = number of atom x atomic mass of the atom

For H2O

Number of H atoms = 2

Number of O atom = 1

Molecular weight of H2O = 2(mass of H atom) + 1(mass of O atom)

Molecular weight = 2(1.00784) + 15.999

= 18.01558 u

= 18.016 u
