B. Tums (500 mg CaCO3 per tablet) – 150 tablets for $5.49
C. Phillips (1200 mg Mg(OH)2 per 15 mL) – 769 mL for $9.99

first calcluate the price per mole
Example: A. moles=.550/molmassCaCO3 +.110/molmassMg(OH)2
price per mole= 9.44/moles
Do this for the other two.
C. moles=1.200/molmassMg(OH)2 Price /mole=9.99/molemassMg(OH)2
Now,because the acid neutralizing of all three is the same on a MOLE basis, the above listing of price/mole tells you the price compared on an equal acid neutralizing basis.
