Use this equation: HCl(aq) + NaHCO3(aq) = H20(l) + CO2(g) + NaCl (aq).
If one tablet costs 15 cents, calculate the cost of neutralizing stomach acid (HCl), in dollars per mole of HCl neutralized.

Sorry! 1 tablet contain 1.87g NaHCO3.

per mole of HCl will need 1 mole NaHCO3.
molecular wt of NaHCO3 = 23+1+12+48=84.
1 tablet contains 1.87 gms of NaHCO3.
84 gm NaHCO3 is contained by 84/1.87 = 44.91 = 45 tablets
it will cost 45x15= 675 cents= 6.75$

How may moles of NaHCO3 are you going to allow me to buy for my $0.15. Or how many moles are in one tablet?

you need to know how many moles are in a tablet ... or how many tablets were used
