 Okay, let's try this one. Calculate the pH of the solution, which the H plus concentration, 3.6 times 10 to the negative fourth mole, okay? So remember to get the pH, right? Negative log of H plus or H3O plus, same thing, okay? Do we have H plus concentration? Yes. All we do is plug that in. The pH doesn't have units, okay? Just pH units. So in this calculator, which is kind of janky relative to mine, you do 3.6 and then you put exponent, then you put four and then negative, enter, then log that and then multiply that by negative one. And what I get is hopefully the same thing that you guys get. What did you guys get? 3.4. Yeah, in this case, 3.44, okay? These weird sig fig rules, okay? You got to add one more to what they have here. I won't be too much of a stickler on it, but just keep it in mind, okay? Is everybody okay with getting that answer? Okay, 3.4.
