if the ph of a solution is 1.50, what is the hydronium concentration?
1. 6.7 x 10^-3 M (exponent neg. 3)
2. 1.5 x 10^-14 M (exponent neg. 14)
3. 0.032 M
4. 0.15 M

Punch this into your calculator 10 ^ -1.50 This will give you the hydronium concentration in M

the answer would be #3 0.032 because pH = - log [H3O+] so the [H3O+] = 10^ -ph, which in this case is 1.5 and 10^-1.5 = 0.032

pH = -log(hydronium conc.)
10^(-pH) = hydronium
10^(-1.5) = ans

[H] = antilog (-pH)
= antilog (-1.5)
