Click and drag on elements in orderPlace the following steps in the order you would use to calculate the Ka for a 0.100M solution of HF at equilibrium.Instructions

1.0 mole of a weak acid HA was dissolved in 2.0 L of solution. After the system had come to equilibrium, the concentration of HA was found to be 0.34 M. Calculate Ka for HA.

Calculate [H+] of 0.100M HNO2 (Ka = 6.0×10-4

14. 0.2 m aqueous solution of KCl freezes at -0.68°C calculate van't Hoff factor. kf, for water is 1.86 K kg mol¹. ​

Calculate the Ka for a 0.50M weak acid solution that has a pH equal to 4.15.2.33 x 10-93.21 x 10-71.00 x 10-87.59 x 10-8

What is the pH of a aqueous buffer solution that is made of 0.387 M HF(aq) and 0.061 M KF(aq)?For HF, Ka = 3.548 x 10-4.Give your answer with 3 significant figures.
