Kev daws qhov teeb meem Acid-Base Neutralization Kauj Ruam 1: Muab xam cov moles ntawm OH-. Molarity = moles / ntim. moles = Molarity x Volume. moles OH- = 0.02 M/100 milliliters. Kauj ruam 2: Xam qhov ntim ntawm HCl xav tau. Molarity = moles / ntim. Volume = moles/molarity. Volume = moles H+/0.075 Molarity
