Question

Please help!!

1. What is the molarity ([H+]) of a solution that has a pH of 4.73?

2. What is the pOH if the pH of a solution is 5.6?

3. what is the pH of a solution that has a [H+] of 1.659×10^-9 M?

Answer 1

ok so number 3 for solving for the M nothing can really be further done, 1.659x(10^-9m)......Since the exponent of the scientific notation is negative

−

9

, move the decimal point
