Im doing this thing online for chem, and i cant figure this out. to find the formula weight of CaCO3 dont you just take 100.087 x 1.66X10^-24?

Its not working for me...

thanks
 
Ca = 40.07
C = 12.01
O = 16.00

40.07 + 12.01 + 16.00*3 = molecular mass (in grams for one mole of CaCO3, in AMU for one molecule of CaCO3)
