Web1 mole = 6.02 x 10^23. Therefore, 1 mole of amus = 1 mole of 1.6605 x 10^ (-27) kg = 6.02x10^23 of 1.6605 x 10^ (-27) kg = 6.02x10^23 x 1.6605 x 10^ (-27) kg ("of" means "x") = 0.001kg = 1g (Please note: Some of the numbers above have been approximated and rounded but for simplicity I've left that stuff out.) WebMrs. Patterson Period 1 Objective 2: Use molar mass to convert between mass in grams and amount in moles of a chemical compound. Objective 3: Calculate the number of molecules, formula units, or ions in a given molar amount of a chemical compound. Molar mass can be used as a conversion factor for converting grams to moles and moles to …
