Arthur Wen, a CHEM 18.1 student, was tasked to make a 250mL solution of NaCH3COO with pH = 9.022 for their laboratory class. However, he forgot to take note of the initial concentration needed and was too shy to ask Mr. Lee, his teacher. He knows that the conjugate acid of one of the salt's ions has a Ka = 1.8 x 10-5. 1. Compute for the initial concentration (M) of NaCH3COO: M 2. Compute the mass (g) of solid NaCH3COO to prepare the said solution:
