Complete combustion of 6.70 g of a hydrocarbon produced 21.4 g of CO2 and 7.67 g of H2O. What is the empirical formula for the hydrocarbon? Insert subscripts as necessary.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

Empirical formula :-
The simplest formula of a compound which shows only relative number of atoms of different elements present in a molecule of the compound is called empirical formula .
To find empirical formula following procedure should be followed
i) find percentage of elements
ii) Divide percentages of elements with their respective atomic weights to get atomic ratios.
iii) select smallest atomic ratio and divide all values with this to get simplest ratio of atoms .
If simplest ratio is not integer then multiply all values with suitable number to get integer value.
Simplest ratio corresponds to empirical formula .
