Answer to Question #14012 in Physical Chemistry for William Buford
How many moles of zinc are there in 0.172 grams of the metal?
You must first know the molar mass of zinc. It is 65.4 g/mol. Now you can calculate the number of moles: 0.172 g x (1 mol / 65.4 g) = 0.003 mol (the grams cancel each other out, leaving you with just moles)
