Okay, So, first question, we have to calculate the pitch on the p o h of our awkward solutions at attempt a cure of 298 Kelvin, the report A We have a constitution of always two women at the pool is equal to the native log. Oh, the concentration of our so h minus said at one point go 10 to 6. Taking that into captivity. We have six, and we you call that the pH P O H 26 is equal to 40. So we see that r p H is equal to eight, and we could do the same for 40. We have that are appealing. Physical, too. Negative log of 6.5 times 10 to the negative force, which gives me 3.2 and solving our pH feel h is equal to 14. Equation. You see that P. H is equal to 10.8. Okay, No reports. He has a concentration of h plus. So I mean, the pH is people sitting like a log, uh, 3.6 times 10 to the night of nights. And that gives me 8.4 and we get a pillow difficult to 14 minus 8.4, which used a 5.6. And lastly, we have party, so we have a pH. You be good tonight. 2.5 time tension in the room, too. And that gives me one point appeal, which is equal to 14 minus 1.6, which gives me 12 point work.
