Question

Chemistry

Use the Henderson-Hasselbach equation to calculate the pH ofeach solution:

I figured out part A by myself because the numbers were alreadyin Molarity for me so I just plugged in numbers and calculated.

B. A solution that contains 0.785% C5H5N by mass and 0.985%C5H5NHCl by mass. (Here, I don't know what to do with the %'s toget the molarity in order to find the pH.)

C. A solution that contains 15.0 g of HF and 25.0 g of NaF in125 mL of solution. (Here,i thought i could just use the g and mLto find molarity using mol/L but that led me to the wronganswers.)

Please explain your process clearly as possible because I wouldreally like to be prepared when i see these kinds of questions onmy exam. Thanks!
