Interpretation:
The empirical formula and the name of the compound that contains
Concept introduction:
An empirical formula gives the simplest whole number ratio of atoms of each element present in a compound.
Following are the steps to determine the empirical formula of a compound when the masses of each element are given,
Step 1: Divide mass of each element by its molar mass to convert the mass of the element to moles. The formula to calculate moles from the mass is as follows:
Step 2: The number of moles of the elements is the fractional amounts, thus, write the calculated amount
Step 3: Convert the moles of each element to the whole number subscripts. The steps for this math conversion are as follows:
(a) Each subscript is divided by the smallest subscript.
(b) If the whole number is not obtained after division, multiply the obtained subscripts by the smallest integer.
