How do you calculate the molecular formula of a substance which contain 80 percent C and 20 percent H?
You can only calculate the empirical formula because you do not have a mass of this compound given. To do the empirical formula assume 100 grams and change percent to grams. Get moles. 80 grams Carbon (1 mole C/12.01 grams) = 6.66 moles C 20 grams hydrogen (1 mole H/1.008 grams) = 19.84 moles H the smallest becomes 1 in the empirical formula and the other number is divided by it, Thus; H/C 19.84 moles H/6.66 moles C = 2.9, which we call 3 so, CH3 --------------- is the empirical formula To get the molecular formula tour question needed to read; How to calculate molecular formula from such ans such mass of compound with these percentages of elements, Which, of course, your question did not provide. Then you would have divided that given mass by the mass total of the elements of the empirical formula, got a whole number by which you would have multiplied the numbers of your empirical formula to get molecular formula.
What is meant by law of constant proportion and how is this law applied in experiment empirical formula of a compound?
The law of constant proportion states that a pure chemical compound always contains exactly the same proportion of elements by mass.This information, together with the atomic masses of the elements in the compound enable scientists to determine the formula of a compound.

The empirical formula for acetylene?
The empirical formula for acetylene is C2H2, which indicates that one molecule of acetylene contains two carbon atoms and two hydrogen atoms.
What is the empirical formula for water?
The empirical formula for water is H2O, indicating that each molecule of water contains 2 hydrogen atoms and 1 oxygen atom.
Empirical formula for silver oxide?
The empirical formula for silver oxide is Ag2O, which indicates that the compound contains twice as many silver atoms as oxygen atoms.
What is the empirical formula of C10H4?
It is an empirical formula.
Determine the molecular formula of a compound if its empirical formula is C2H6O and its molar mass is 138g?
To determine the molecular formula from the empirical formula and molar mass, first find the empirical formula mass by adding the atomic masses of the atoms in the empirical formula. Then, calculate the ratio of the molar mass given to the empirical formula mass. Finally, multiply the subscripts in the empirical formula by this ratio to find the molecular formula; for this case, the molecular formula is C6H18O3.
The lowest whole number ratio of the elements in a compound is called the?
The lowest whole number ratio of elements in a compound is called the empirical formula. This formula shows the simplest whole-number ratio of atoms in a compound.
What the empirical formula for c12h12?
The empirical formula for C12H12 is CH. The empirical formula represents the simplest whole-number ratio of elements in a compound.
What is the relationship between a empirical formula and formula unit?
The empirical formula represents the simplest whole-number ratio of atoms in a compound, while the formula unit represents the combination of ions in an ionic compound. The empirical formula is used for covalent compounds, while the formula unit is used for ionic compounds.
What is the relationship between empirical formula and formula unit?
A formula unit is an empirical formula.
How do you know if a formula is an empirical formula?
An empirical formula has no data about the structure of a compound.
What is the emperical formula of water?
The empirical formula of water is H2O.
What is the empirical formula of azulene?
It has a molecular formula of C10H8 so that would make an empirical formula of C5H4.
