@X@user.full_name@X@ @GMU: When 12.981 g of Ga reacted with an excess of oxygen, a total of 8.081 g of Ga2O3 formed? What was the percent yield?4Ga(s) + 3O2(g) → 2Ga2O3(s)

@X@user.full_name@X@ @GMU: A 58.96 mL sample of H2SO4 was neutralized by exactly 35.51 mL of 0.1409M Ca(OH)2. What was the molarity of H2SO4?H2SO4(aq) + Ca(OH)2(aq) → CaSO4(aq) + 2H2O(l)
