MOLECULAR FORMULA DEFINITION
A formula which tells the actual number of atoms present in a molecule of a substance is known as molecular formula.
Examples: H2O2 and C6H12O6 are the molecular formulas of hydrogen peroxide and glucose respectively.

What Can You Do With An Associates Degree In Chemistry?
The associate degree (AD) in Chemistry, equivalent to the European level 5, is a two-year higher professional education between the four-year MBO (level 4) and the four-year HBO bachelor (level 6). Many people think a four-year bachelor’s degree is far too long, especially if you want to do it part-time, you are vulnerable, because work,…
Why fish and plants survive underneath water in winter?
The lower density of ice than liquid water at 0°C compels water in ponds and lakes to freeze from surface to the downward direction. Water attains the temperature of 4°C by the fall of temperature in the surrounding. As the outer atmosphere becomes further cold, the water at the surface becomes less dense. This less…
What are Average Atomic Masses?
Many elements exist as a mixture of their isotopes. The atomic masses of such elements depend upon the number of their isotopes and their natural abundances. This is why their atomic masses are in fraction. This can be explained through following example, EXAMPLE: A sample of neon is found to consist of 20Ne, 21Ne and…
How to do Dimensional Analysis in Chemistry?
Dimensional analysis in Chemistry is often a tricky concept for students to get. Still, it is a significant one and one that you will use throughout all of your chemistry classes. Dimensional analysis is the process we use to convert a value from one unit or set of units to another. Some important questions to…
Law of conservation of mass
This Law was given by Mikhail Lomonosov. This law states that “the total mass can neither be created nor destroyed but can be converted from one form to another during a chemical reaction”. Explanation: Since all the matter is composed of atoms, therefore, atoms can neither be created nor destroyed during a chemical reaction. Total…
Graham’s Law of Diffusion Definition
“The rates of diffusion of two gases are inversely proportional to the square roots of their densities or molecular weights at the same temperature and pressure”. Mathematical formula: Graham’s Law of Diffusion Equation, Where r1 and r2 are the rates of diffusion of two gases, d1 and d2 are their densities and M1 and M2…
