Dear studentpH=2 thus H+ = 10^-2pH=4 thus H+ = 10^-4pH of resulting solution when two acids are mixed in it are :-N1V1 + N2V2 = NfVf10^-2 * 1 + 10^-4 * z = 10^2.75 *(1+z) = 0.00177 (1+z)0.01 + 0.0001 z = 0.00177 (1 +z)On solving we get,z= 4.92 which is approximately 5Kindly post each question separately.
