It is a poor chemical formula. Poor, because it would not distinguish between acetylene C2H2 and benzene C6H6 for example. It is useful only to the extent that it shows the proportions of the atoms in molecule of the compound.
The fewer the number of sides that a polygon has, the higher the surface area to volume ratio. This increases until the polygon has an infinite number of sides, or has become a perfect sphere, when the ratio is the smallest.
an empirical formula For an ionic compound, the empirical formula is called a formula unit.
Formula to calculate the ratio
3:2
A percent is a ratio of a number to 100.
Emperical formula give the smallest whole number ratio of atoms in a compound
The empirical formula is the smallest whole number ratio of different elements in a molecule. The molecular formula has the actual number of atoms of different elements in a molecule
On one of your quizes? I read that it is.
formula unit
the empirical formula
the lowest whole number ratio of elements in a compound A+
The ratio is 1:1. The formula is Mg2Cl2
The lowest whole-number ratio of atoms in a molecule
The chemical formula in which the subscripts are given in the smallest ratio.
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.
