A person takes `6.1 g` of an anta-acid tablet comprising bicarbonate ion at 20.8%. The volume of `CO_(2)` evolved at (1 atm and `25^(@)C`) in the stomach (on neutralisation) multipled by a factor of '10' will be `x L`. Calculate the approximate (integer) value of `x`.

Text Solution

Verified by Experts

`HCO_(3)^(ɵ) rarr CO_(2)`
Moles `HCO_(3)^(ɵ)`
`= (6.1 g)/(61) xx (20.8)/(100) = 0.0286` moles of `CO_(2)`.
1 mol `CO_(2)` at 1 atm, and `25^(@)C = 24.4 L`
`0.0308 "mol" CO_(2) = 24.4 xx 0.0286 "moles of" CO_(2)`
`V_(Co2) = 0.7 xx 10 = 7 L`
