Calculate the PH concentrated hydrochloric acid if this solution is 24.8% HCL by weight and has a density of 1.16g/ml. I do not understand the right answer 0.90PH Why? Please help
My calculation
1.18g/ml x 1000ml x 0.248/36.5 = 7.8M
I cannot do?

I think your 7.8 is ok if you carried it out one more place. I obtained 7.88. Then pH = -log(H^+) = -log(7.88) = 0.8966 which rounds to 0.90 to two s.f.
