First step is to get the mass of water molecule in grams:
From the periodic table:
molar mass of hydrogen is 1
molar mass of oxygen is 16
molar mass of a water molecule = 2(1) + 16 = 18 gm
Now, to convert the gm into amu, all you have to do is multiply the gm you got by Avogadro's number as follows:
mass of water molecule = 18 x 6.22 x 10^23 = 1.1196 x 10^25 amu which is approximately 1 x 10^25 amu

Answer:
1.40 moles.
Explanation:
The balanced chemical equation for the reaction of Phosphorus and Oxygen is as follows -

In Part A, the oxygen was taken in excess. So Phosphorus will be the limiting reagent.
Since, 2 moles of
is formed by 4 moles of 
So, for 1.8 moles of
amount of required moles of
=
In Part B, the phosphorus was taken in excess so oxygen will be the limiting reagent.
Since, 2 moles of
is formed by 5 moles of oxygen
So, for 1.40 moles of
moles of
required = 
Thus as of now we have 3.60 moles of
and 3.50 moles of
.
As in the reaction of formation of
, oxygen is the limiting reagent.
So the moles of
formed by the 3.50 moles of oxygen will be
=
= 1.40 moles.
