An antacid tablet contains $0.400 g$ of $Mg (OH) X_{2}$ and $0.300 g$ of $Al (OH) X_{3}$ . Using atomic masses H = 1, O = 16, Mg = 24 and Al = 27, find the volume in mL of $0.100 M$ $HCl$ that the tablet can neutralise completely. Give the answer to the nearest integer.

Numerical answer type, answer in mL, tolerance 0.5.

Answer: 253 mL

Moles of HCl = 2(0.400/58) + 3(0.300/78) = 0.01379 + 0.01154 = 0.02533 mol. Volume of 0.100 M acid = 0.02533/0.100 = 0.25332 L = 253.32 mL, which is 253 mL to the nearest integer.
