To find the mass in grams of 12.5 moles of Ba(OH)2, we first need to calculate the molar mass of Ba(OH)2. The molar mass of Ba(OH)2 is calculated as follows: Ba = 137.33 g/mol, O = 16.00 g/mol, H = 1.01 g/mol. Therefore, the molar mass of Ba(OH)2 = 137.33 + (2*16.00) + (2*1.01) = 171.35 g/mol. Then, the mass of 12.5 moles of Ba(OH)2 = 12.5 moles * 171.35 g/mol = 2143.75 g, which is 2.14 x 10^3 g.
