QUESTION 18 How many grams of sodium acetate (C,H,0,Na) need to be dissolved in 180 mL of a 0.377 M acetic acid (HC,H 0,, K = 1.8 x 10) solution, so that the concentration of acetate is equal to the concentration of the acetic acid? Report your answer to THREE significant figures. QUESTION 19 The solubility product constant for a certain metal phosphate, M3(PO,), is K. = 5.7 x 10-39 Its molar mass is M= 226.02 g/mol. What is its solubility in mol/L? Report your answer to TWO significant figures. You may (but are not required to) enter your answer in scientific notation; for example, if your answer is 2.4 x 10-2 you would enter 2.4E-2. The E must be uppercase
