Balanced Equation is: 2HCl + Ca(OH)2 --> 2H2O + CaCl2 So you need 1 mole of Ca(OH)2 for every mole of HCl. 2 moles HCl / 1 mole Ca(OH)2
1 mole KClO3 / 6 moles KOH
Total mass = 15x5 = 75g of BaTi(SiO3)3 n = m / M n = 75g / 413.45 g/mol n = 0.181 moles BaTi(SiO3)3 0.181 moles BaTi(SiO3)3 * (3 moles Si / 1 mole BaTi(SiO3)3 = 0.544 moles of Si
