These have no net charge and have mass slightly more than that of protons. Neutrons are the subatomic particles present in atomic nuclei like protons. Mass number is an integer equal to the sum of the number of protons and neutrons of an atomic nucleus. It is a portable molecular mass calculator for Windows.In this article, we will learn how to calculate mass number(A) but first off, lets define it. Write it as CuSO4H10O5.Īlong with the molecular mass of the compound, it also shows some additional information: Hence, you have to write it by multiplying 3 with all atoms inside the brackets, i.e., FeO3H3. For example, if you write Fe(OH)3 as it is, it either shows an error message or calculates its incorrect molecular mass. You cannot enter the chemical formula of all chemical compounds in their original format. Moleculator accepts different formats for different chemical compounds. Just enter the formula of a compound, the molar mass of which you want to calculate and hit Enter button. Though it is a command line tool, it is very simple to use. Moleculator is a command line tool to calculate the molar mass of different elements/compounds. For example, if you want to calculate the molar mass of Sodium hydroxide: Na(OH)2, which includes brackets in its formula, you cannot write it in its original format. MoleCalc does not accept special characters. MoleCalc comes with a built-in periodic table. It calculates the molar mass in real time as you start entering the elements one after the other. For example, in order to form the molecular formula of Glucose which is C6H12O6, firstly, you have to enter the symbol of first element Carbon and its number (6), then Hydrogen and its number (12), and last, Oxygen and its number (6). ![]() This can be done by entering the symbol of an element and number of elements. Instead, you have to form the molecular formula by adding elements one by one. In this calculator, you cannot add the complete molecular formula of a compound at a time. MoleCalc is another free molecular mass calculator for Windows. You may also like some best free System Of Linear Equation, Factoring Quadratics, and BMI calculators for Windows. You can also go for McDalton and Molecular Weight Calculator software which are good molar mass calculators Besides this, you can also form a chemical formula by inserting elements directly from built-in Periodic Table. ![]() First of all, it lets you input the chemical formula of all compounds in their original formats. My favorite molecular mass calculator:Ĭhemiasoft – Molecular Weight Calculator is my favorite molar mass calculator. I also added a command line tool in this list which is a portable software and very easy to use. These tools include formula finder, math calculator, capillary distribution calculator, pH & pOH calculator, half-life calculator, etc. Some molecular mass calculators come with built-in Periodic Table for reference.Īs you read the article, you will also find some calculator which come with some more useful tools. You will also find a calculator which lets you display the result up to 3 decimal places. For example, to calculate the molecular mass of Na(OH)2, you have to enter it as NaO2H2. Such types of molecular mass calculator require different formats for different chemical compounds. While some calculators let you enter the chemical formula in the original format, some do not. Using these free molecular mass calculator, you can calculate the molar mass of simple to complex chemical compounds. Here is a list of Best Free Molecular Mass Calculator For Windows.
