A chemistry graduate student is given 300. mL of a 1.80M benzoic acid (HC,H,CO₂) solution. Benzoic acid is a weak acid with K-6.3 x 105. What mass of NaC, H,CO₂ should the student dissolve in the HC H,CO₂ solution to turn it into a buffer with pH = 4.66? You may assume that the volume of the solution doesn't change when the NaC,H,CO₂ is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits. 0 X G OL

Notes
A chemistry graduate student is given 300. mL of a 1.80M benzoic acid (HC,H,CO₂) solution. Benzoic acid is a weak acid with K-6.3 x 105. What mass of
NaC, H,CO, should the student dissolve in the HC H₂CO₂ solution to turn it into a buffer with pH = 4.66?
Check
You may assume that the volume of the solution doesn't change when the NaC H,CO₂ is dissolved in it. Be sure your answer has a unit symbol, and round it
to 2 significant digits.
