Explanation:
Molecular formulas show correct and accurate number of each type of the atoms which are present in molecule.
On the other hand, structural formulas show arrangement of atoms and covalent bonds between them.
For example,
The molecular formula for carbon dioxide is
The structural formula is O = C = O
The number of moles of carbon atoms that are in 0.45 moles of C3H6O is 1.35 moles
step by step explanation
Find the total number of carbon atom in C3H6O
that is 1 x 3 = 3 atoms
0.45 moles is for one atom
what about 3 atoms
by cross multiplication
3 x0.45 = 1.35 moles
Yes because if it has different number of neutrons it could be a type of isotope
