how ,amy grams of aspirin are required to react exactly with 29.40ml of a 0.6M solution of sodium hydroxide

Write the equation.
aspirin + NaOH ==> Aspirin*sodium salt + H2O
2. Calculate moles of NaOH. That will be M x L = ??
3. The equation you have written should give you a 1:1 ratio of aspirin to NaOH.
4. Therefore, moles aspirin = moles NaOH
5. Now convert moles aspirin to grams. # grams = moles aspirin x molar mass aspirin. You can obtain the molar mass of aspirin here.
Post your work if you get stuck.
