How many moles is each of the following?
take wt of compound divide by molar wt gives number of moles


molar wt of a compound (mw) is found by adding the mw of each and every element the compound contains


ill do one


60.7 g CL2


1 atom of cl has a mw is 35.4 g/mole


so cl2 is 2 times that or 70.9g/m


so 60.7 cl2 / 70.9 = .856 moles
