Hey everyone I have a couple of questions which in help in terms of the maths.

1) 50mL of 1.1 mol/L HCl is mixed with 100mL of 0.4 mol/L NaOH. What is the pH of the resultant solution? {2 marks}

2) A 200mL solution of 0.04 mol/L HCl acid is diluted to produce a solution with a total volume of 20L. Calculate the final pH of the solution. {2 marks}

3)For 0.002 mol/L HCl, what volume of acid is required to produce a solution of pH 1.5? {2 marks}

Thanks in advance to any responses!
