How many moles are there in 50 g of lithium
WebUsing the generic expression to convert g to atoms: Number of Atoms = (Given Mass/Molar Mass) * Avogadro’s Number Number of Atoms = (78/40.078) * 6.02 * 10^ {23} Number of Atoms = 1.9462 * 6.02 * 10^ {23} Number of Atoms = 1.171 * 10^ {+24} For further verification, you can let this grams to atoms calculator do that for you in seconds. WebLithium for instance has an atomic mass of 6.941 grams and this is equal to one mole of lithium. This is why we state the atomic and molecular masses in units of grams per mole or g/mol. What can we do with moles? We use the unit to make calculations based on balanced chemical equations.
