If you divide the number of atoms of a single isotope by the total number of atoms, you get the ratio of that isotope. This tells you how common/uncommon that isotope is.
This ratio is different for each compound; for the oxide P4O10 the ratio is 2/5.
2:1 ratio. There would be eight atoms of hydrogen and four atoms of oxygen.
The ratio Na/Cl is 1 in the formula unit.
All sugars are carbohydrates, with the general ratio Cx(H2O)y. There are thus 2 moles of H atoms to 1 mole of C atoms.
If you divide the number of atoms of a single isotope by the total number of atoms, you get the ratio of that isotope. This tells you how common/uncommon that isotope is.
Ratio ???? If you mean the formula, then aluminium chloride is 'AlCl3'. This formula tells that there are 3 atoms of chlorine and one atom of aluminium .
This ratio is 2/5.
This ratio is different for each compound; for the oxide P4O10 the ratio is 2/5.
The chemical formula of potassium nitride is K3N. The ratio potassium atoms/nitrogen atoms is 3.
The ratio of atoms in monosaccharides is 1 carbon: 2 hydrogen: 1 oxygen.
A chemical formula gives the number ratio of the different kinds of atoms present in the compound. This means that the ratios are the same if you count in individual atoms, dozens of atoms, or molecules of atoms.
The ratio (as atoms) carbon/oxigen in graphitic oxides is between 2,1 and 2,9.
2:4
1:1
C to O in the ratio 1 : 2.
3 : 2
