Question

One molecule of water $$(H_{2}O)$$ contains two atoms of hydrogen and one atom of oxygen. A hydrogen atom has a mass of $$1.0\ u$$ and an atom of oxygen has a mass of $$16\ u$$, approximately.
What is the mass in kilograms of one molecule of water?


Solution

As we know,
 In atomic mass units, the mass of one molecule is $$(16+1+1)u=18\ u$$. Using Eq $$1-9$$ we find
$$18\ u=(18\ u)\left(\dfrac{1.6605402\times 10^{-27}\ kg}{lu}\right)=3.0\times 10^{-26}kg$$
