How do you solve this?

Question

Sodium hydrogen carbonate NaHCO3, also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid HCl

, which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO3

 neutralizes excess HCl

 through this reaction:

HCl(aq) + NaHCO3(aq) → NaCl(aq) + H2O(l) + CO2(g)

The CO2 gas produced is what makes you burp after drinking the solution.Suppose the fluid in the stomach of a man suffering from indigestion can be considered to be 200.mL

 of a 0.089

 M HCl

 solution. What mass of NaHCO3

 would he need to ingest to neutralize this much HCl

 ? Round your answer to 2

 significant digits.

Answer 1

Start with an amount of something to get to amount of something else. Use unit canelling to tell you what to multiply and divide and what information you need.

200 ml HCL soln. (liters/1000ml)(.089 moles HCl/liter soln.)(1 mole SB/1mole HCl)( g/mole SB) = g SB

Once you know the method, these problems are straightforward.
