What mass of lithium fluoride will I produce if i started with 10g of fluorine?
Well, first of all you’ll need a balanced chemical formula showing the reaction between lithium and fluorine forming lithium fluoride. Li + F = LiF This reaction is already balanced so let’s move on to solving the problem. This is a stoichiometry problem. You start off with 10 grams of F you’ll need to convert this to LiF and then solve for grams. Convert 10 grams of F to moles by dividing 10 by the molar mass of F which is 19. Now that you have 1 mole of F you will notice that 1 mole of F equals 1 mole of LiF. Now you’ll need to convert moles of LiF to grams by multiplying by its molar mass which is 26 grams. Here’s how it looks like: 10 g F x 1 mole F/19 g F x 1 mol LiF/1 mole F x 26 g LiF/1 mole LiF this equals 13.7 g LiF I hope this helps.
