Mole: A mole is Avogadro's number of atoms or molecules or particles. Mole Ratio General Chemical Formula: AaBbCc... where the capital letters represent the atomic elements and the small letters represent the number of moles. Next, we will look at two examples of chemical formulas and we...
1. Find the Number of Moles of Each Element The molar mass of hydrogen is 1 g (rounding to one decimal place), so the number of moles present in the compound is 0.675/1 = 0.675. The molar mass of oxygen is 16 g, and the molar mass of calcium is 40.1 g. Performing the same ...

First, convert the grams to moles using the molar mass and then use Avogadro's number to find the number of molecules: \(\mathrm{2g\enspace NaCl\Biggl(\dfrac{1mol\enspace NaCl}{58.44g\enspace NaCl}\Biggr)\Biggl(\dfrac{6.022\times10^{23}\enspace molecules\enspace NaCl}{1mol}\Big...
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 conversion of grams to moles, and vice versa....
