A guide on how to calculate Molecular weight
Molecules are considered to be fundamental parts of chemistry and the world of science. it is no wonder then calculating molecular weight or the number of molecules present is such an important thing.
To understand how molecular weight is calculated, let’s take a sample calculation. For example, water which is H2O when discussed in chemical formulas is a molecule.
Now, this molecule has about three atoms. Two of these atoms are hydrogen while one of them is oxygen. The atomic weight of oxygen is pegged at 16 while that of hydrogen stays at one.
If you want to calculate the molecular weight of water, then you have to do a few things. The first thing will be to take the atoms and their contributions. You then add them up. this will give you 18 (grams).
Still, confused? Let’s take another example. The formula that works for ethylene monomer has about six atoms. The weight of carbon is set at 12 while hydrogen is just one. The total molecular weight will be 28. It’s that easy.
Another thing that can help you know how to calculate the molecular weight better is by knowing what a mole is.
A mole is often referred to as the symbol of the amount of substance present at any given time. It is considered to be the fundamental unit indicating substance present.
How to get better at Molecular weight calculation
If you are trying to improve in calculating the molecular weight, then you are doing a wonderful thing. There are somethings that can help you reach your goal faster.
Calculate other elements
The periodic table is alive. This means that you know all the elements and their atomic weight. It’s time to use this to your advantage. If you are trying to get better, take your time and calculate the other elements. This will help.
As they say, you go faster when you work harder. Sometimes, all you need to be better at something is practice. Take your time to practice your calculations.
Soon enough, you will realize how much you have improved in such a short period of time. When you are done, you can simply check your answer using a molecular weight calculator.
If you have learned how molecular weight calculations work, then it might just be time to get a molecular weight calculator.
There are so many benefits that come from using these calculators. They include more time as well as ease of operations. Using them will always be a win-win scenario.
Looking for an MW calculator? The good news is that it can be found on most sites. Therefore, you should have no problems at all.
Getting your calculations right with molecular weight can be quite a fulfilling experience. Following the tips we have outlined will definitely get you closer to your goal.
If you are already an expert, then you should probably get a calculator for yourself. It’s affordable and a wise move to make.
