Balanced equation is as follows
Mass of HCl produced per day =3×2.6=7.8g
Now, stoichiometry indicates that 109.5g of HCl is generated/neutralised by 78g of Al(OH)3.
7.8g of HCl is neutralised by

78

109.5

×7.8
=5.556g of Al(OH)3
Now, for 400‌mg or

400

1000

g of Al(OH)2=1 tablet
∴ 5.556g of Al(OH)3=

1000

400

×5.556
=13.89 tablets
=14 antacid tablets.
