45.1 ml of 0.104 mm hcl solution is needed to neutralize a solution of koh , 0.294 grams of koh must be present in the solution
MHCl*VHCl = MKOH*VKOH = moles of KOH
moles of KOH = 0.116 M x (45.2/1000) L = 5.24 x 10^-3 mol
molar mass of KOH = 56.1 g/mol
mass of KOH = molar mass x moles = 56.1 x 5.24 x 10^-3 = 0.294 g
