To calculate the number of moles of a solute, you need two pieces of information, which you may have to infer from other data. The first is the chemical formula of the solute, and the second is the mass of the solute. You then calculate molarity by measuring the volume of the solution...
To calculate the molecular mass of a compound, you need to know two things. The first is the molecular formula, and the second is the atomic mass number of each of the elements that comprise it. The atomic mass number for each element is listed in atomic mass units under its symbol in ...
What is atomic mass and how to measure the atomic mass of a proton? Atomic mass refers to the weight of subatomic particles (Electron, Neutron, and proton). Learn more about Atoms and Molecules here in detail. Ways to Calculate the Mass of Proton There are three ways to find the mass...
If you see "normal" as "expected," even in the chemical sense this is more or less on target: A normalized preparation is one that has been created in proportion or relation to an established standard. To discover how to calculate the normality of NaOH, or how to convert from normality ...
100 = 40 per cent how to calculate the percentage of a number? to calculate the percentage of a number, we need to use a different formula such as: p% of number = x where x is the required percentage. if we remove the % sign, then we need to express the above formulas as; p/...
Chemistry is full of many different confusing conversions. These conversions are important because they ultimately allow us to discover how a particular atom or molecule will interact with other atoms and molecules. Central to chemical conversions is the

How to Calculate the Molar Mass More Details on the Calculation Definition The molar mass can be defined as the mass of one mole of any substance. As for a mole, that’s just the overall number of atoms in twelve grams of the carbon-12 isotope. That’s always a fixed number, often ...
How to Calculate Mole Fractions Using Mass Percent If you know the percent by weight of a solution, you can find the weight of solute. Divide this by its molecular weight to find the number of moles and divide by the volume of solution to find the molarity....
How to Calculate the Stoichiometric Ratio. Stoichiometry is a type of math associated with chemistry. In stoichiometry, you perform calculations pertaining to moles (the basic unit of weight in chemistry), masses and percentages. A stoichiometric ratio s
