Gastric juice contains 3g `HCl` per liter. If a person produces 2.5 L of gastric juice per day, how many antacid tables each containing 400 mg of `Al(OH)_(3)` are needed to neutralize all the `HCl` produced in one day ?

`~~13`

Text Solution

Verified by Experts

The correct Answer is:

`"geq of "HCl=(3)/(36.5)xx2.5=0.20548`
`="geq of "Al(OH)_(3)`
`"Weight of "Al(OH)_(3)=(0.20548xx78)/(3)=5.342g=5342mg`
`therefore" No of tablets "=(5342)/(400)=13.35=14`
