Determine the mass of NH2CH2CO2Na and the volume of 0.150 M HCl solution required to make 1.35 L of a buffer solution at pH=10.75 and at a total concentration of 0.33 M. pKa(NH2CH2CO2H)=9.88.

a.Mass of NH2CH2CO2Na:
b. Volume of HCl solution:

Hi Im sooo confused.

9.88=10.75+log(0.15/HCL)
-0.87=log(0.15/HCL)
HCL=0.135M
Mass=0.135M(1.35L)(36.46g/mol)
Mass=6.64g

but its wrong what???why?
