Answer:
It may be too late, but you got lost in all that info. All they want is for you to show how many moles in 3.00 grams of Tin metal.
Explanation: I cannot print the dimensional analysis that is asked for, but we can do this.
Let’s use water instead of Tin, then you can figure it out. 1 mole of water is 2 H x 1 amu. 1 O at 16 amu. Forget the amu, just add the 16 + 2= 18 grams of Water In 1 mole. So 9 grams would be how many moles of water? 9 is 1/2 of 18 isn’t it? So it is 0.5 Moles.
