What is the molar mass of KMnO4? Molar Mass: Molar mass is the number of grams of a substance that equals one mole or {eq}6.02 x 10^{23} {/eq} molecules, also known as Avogadro's number. Molar mass can be used to convert between moles and grams, denoted by {eq}g/mol {/eq}...
using molar mass is also possible with a compound molecule. Water is a molecule that has twohydrogenand one oxygen atoms stuck together. Adding all of their mass numbers together gives us the mass of one molecule of water. This number is equivalent to the mass in grams of one mole of ...
A mole is a number of atoms or molecules of a substance or element equal to 6.02 x 10^23 (Avogadro's number). For example: a mole of chlorine is just 6.02 x 10^23 chlorine atoms.The molar mass of a molecule is what the mass would be if you had 6.02 x 10^23 ...
