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+]

.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+]
