What is the hydronium ion concentration in a solution of hcl that has a ph of 4.65?

9.35

Explanation:

pH = 4.65

pOH = ?

But pH + pOH = 14

4.65 + pOH = 14

pOH = 14 - 4.65

pOH = 9.35

The pOH of the solution is 9.35

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
