Reply:i think you're trying to get us to do your homework! %26gt;:(
Reply:Do your own homework... if you paid attention in class, this should be easy.
Reply:you need this formula





number of moles = mass/ relative molecular mass





the relative formula mass can be found by looking at the elements in the Periodic Table (it's the largest number)





Good Luck
