Question

Calculate the hydrogen ion concentration, in moles per liter, for solutions with each of the following pH values.

pH=1.10


im guessing that this is what i did in my previous question except now i have to do it backwards.

but i don't know how to do the calculations on the calculator.

thanks

Answer 1

pH = -log(H^+).
1.10 = -log(H^+)
-1.10 = log(H^+).
Punch in -1.10 on the calculator, look for the 10^x button, punch it, and the answer should come up. If you've done it right, the calculator will show 7.94 x 10^-2 or 0.0794.

Answer 2

yep that's what i got thanks a ton :)
