In chemistry, there are a variety of methods that scientists use to identify a chemical compound, including a molecular formula, molar mass and molecular diagram. The simplest formula of these is ...

Like so many of the chemistry calculator apps out there, this molar mass calculator delivers on exactly what was promised…and not much else. However, sometimes simplicity can go a long way and in that ...

You can work out the molecular formula from the empirical formula, if you know the relative mass formula (M r) of the compound. Add up the atomic masses of the atoms in the empirical formula. The ...

Students learn how to calculate the percent yield for a chemical reaction. Mass/Mass Stoichiometry: Problems and Percent Yield: Students learn how to calculate the percent yield for a chemical ...

Law Of Conservation Of Mass: Did you know that in water the ratio of the mass of hydrogen to the mass of oxygen is always 1:8? This led to one of the laws of chemical combination, the law of constant ...

Atomic Number and Mass Number of Elements: Atoms are the building blocks of matter. They are responsible for the format of all living and non-living things. Understanding their molecular structure and ...

The relative atomic masses of elements are proportional measures. For example, the Ar for helium is 4.0, and the A r for carbon is 12.0. This means that carbon atoms have three times the mass of ...
