How many atoms and molecules are present in 64 grams of sulphur?
12.044*10^23 atoms 1.5055*10^23 S8 molecules
How many GRAMS of aluminum carbonate are present in 7.01E 22 formula units of this compound?
Aluminum carbonate is Al2(CO3)3. If you have 7.0x1022 particles of it, then that's 7.0x1022/6.02x1023 = 0.116 moles. The compound has a molar mass of 234g/mol, so 234x0.116=27.144 grams.
