Academics

Question- A buffer is made by mixing 5.0 mL of 4.0 M NH3 (aq) with 15mL of 2.4 M NH4Cl(aq). What is the pH of the buffer at 25 degrees Celcius , if the base ionization constant of ammonia is 1.8*10^-5 and the ion product of water is 1.0*10^-14 at this temperature?

500mL of 1.00M of NaOH (aq) are mixed with 500mL of 2.00M HCOOH(Aq). What is the pH of the resulting solution , if the acid ionization constant for formic acid is 1.7*10^-4?

Please explain above problem in step by step manner so I can easily understand it
