Question

what is molecular and emphrical formula.​

Answer 1

$\huge\mathfrak\green{Holaa Mate}$

Answer:

The empirical formula of a chemical compound is a representation of the simplest whole number ratio between the elements comprising the compound. The molecular formula is the representation of the actual whole number ratio between the elements of the compound.

Answer 2

Q. What is difference between molecular and empirical formula?

$\huge\mathfrak\</u></strong><strong><u>b</u></strong><strong><u>l</u></strong><strong><u>a</u></strong><strong><u>c</u></strong><strong><u>k</u></strong><strong><u>{</u></strong><strong><u>M</u></strong><strong><u>o</u></strong><strong><u>l</u></strong><strong><u>e</u></strong><strong><u>c</u></strong><strong><u>u</u></strong><strong><u>l</u></strong><strong><u>a</u></strong><strong><u>r</u></strong><strong><u> </u></strong><strong><u>Formula</u></strong><strong><u>}$

✒✒✒✒The formula which gives the actual number of atoms of various elements present in one molecule of the compound is called the molecular formula.

For ex:-

The molecular formula of hydrogen peroxide is H2O2 because one molecule of hydrogen peroxide contain two atome of hydrogen and two atoms of oxygen.

✒✒✒✒The formula which gives the simplest whole number ratio of the atoms of various elements present in one molecule of the compound is called empherical formula.

For example:-

empirical formula of hydrogen peroxide it represents that hydrogen and oxygen are present in the ratio of one ratio one in hydrogen peroxide.

Releation between Empirical and Molecular formula.

$molecular \: formula\: = n(empherical \: formula)$

Where n is a simple whole number ratio having values 1,2,3....

$n = \frac{molecular \: mass}{empirical \: mass}$
