The minimum mass of NaHCO3 that must be added to the spill to neutralize the acid is 27.216 grams
<h3>calculation </h3>
write the balanced chemical equation
2NaHCO3 +H2SO4 → Na2SO4 +2H2O +2CO2
find the moles of H2SO4 = molarity x volume in liters
volume in liters = 27/1000=0.027 l
moles is therefore= 0.027 x6=0.162 moles
by use of mole ratio of NaHCO3: H2SO4 which is 2:1 the moles of NaHCO3=0.162 x2=0.324 moles
mass of NaHCO3= moles of NaHCO3 x molar mass of NaHCO3(84g/mol)
= 84g/mol x 0.324=27.216 grams

Explanation:
Aluminum hydroxide is used as an antacid to counteract hyper acidity associated with the gastritis and peptic ulcer disease which includes duodenal ulcer and gastric ulcer and hiatal hernia.
<u>
Oral dosage (oral suspension)
</u>
Adults
Recommended OTC dose of aluminum hydroxide is 10 mL PO 5—6 times per day, after having meals and at bedtime.
Children
Recommended OTC dose of aluminum hydroxide is 5—15 mL PO every 3—6 hours, or 1 and 3 hours after having meals and at bedtime.
Infants
Recommended OTC dose of aluminum hydroxide is 1—2 mL/kg PO per dose and should be given 1—3 hours after having meals and at bedtime.
