1.	What is the mass of 12.04×10^24 molecules of ammonia?
Answer» MNH3 = 1.75 x 10^24 molecules x 1 MOL/6.02 x 10^23 molecules x 17.03g/1mol (CANCEL out molecules and mol; you'll be left with grams as units). When you perform this CALCULATION, you find out that the mass of 1.75 x 10^24 molecules of NH3 is: 49.5 grams.
