1. Calculate how many milliliters (mL) of 2 M NaOH will be needed to make 0.50 L of a 0.2 M aqueous NaOH solution. 2. You will use a weighted amount of KHP (a weak acid) to standardize your ~ 0.2 M NaOH solution. Assuming that you made exactly 0.2 M NaOH, calculate how many grams of KHP will react with exactly 15 mL of 0.2 M NaOH. Use the information below to help answer this question: _C02 K+ CO2...
