From the coefficients of the equation, we know that for every 3 moles of water consumed, 1 mole of diphosphorus trioxide is consumed.
This means we need to find the mass of 0.75 moles of diphosphorus trioxide.
- The atomic mass of phosphorous is 30.973761998 g/mol.
- The atomic mass of oxygen is 15.9994 g/mol.
So, the formula mass of diphosphorus trioxide is:
- 2(30.973761998)+3(15.9994)=109.945723996 g/mol.
Thus, 0.75 moles have a mass of:
- 0.75(109.945723996), which is about 82.5 g (to 3 sf)
Answer: 
iron atoms
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number 
of particles.
![1 molecule of [tex]Fe_2O_3](https://tex.z-dn.net/?f=1%20molecule%20of%20%5Btex%5DFe_2O_3)
contains= 2 atoms of iron
![1 mole of [tex]Fe_2O_3](https://tex.z-dn.net/?f=1%20mole%20of%20%5Btex%5DFe_2O_3)
contains=
atoms of iron
thus 0.32 moles of 
contains=
atoms of iron
Thus the sample would have iron atoms.
Bond energy is a measure of the bond strength of a chemical bond, and is the amount of energy needed to break the atoms involved in a molecular bond into free atoms.
Answer:
I feel that "The Mesosaurus could not swim between the continents in the open ocean, so the fossils
show that the continents must have been together in the past." Is the best answer.
Explanation:
Because this is a true statement and even scientists belive this is true.
