1. the two strong acids fully dissociate

divide the total moles of H+ by the total solution volume
... this is the concentration of H+ ... [H+]

pH is the negative logarithm of [H+]

3. .050 L * .050 M = .0025 moles ... .150 L * .10 M = .015 moles
... total moles H+ ... .0175

total solution volume ... .050 L + .150 L = .20 L

[H+] = .0175 moles / .20 L = ?

pH = -1 * log[H+]
