LiRa [457]3 years ago
6 0
 Best Answer:<span>  </span><span>The molar mass of Ar = 39.948g/mol 
1mol Ar = 6.022*10^23 atoms 
Therefore 1 atom has mass = 39.948 /(6.022*10^23) = 6.63*10^-23g</span>

Assume the pH of household bleach is 12. What is the hydronium ion concentration in household bleach? What is it hydroxide ion c
Ostrovityanka [42]

Answer:

[H3O+] = 1.0*10^-12 M

[OH-] = 0.01 M

Explanation:

We can use the following equation to find the hydronium ion concentration.  Plug in the pH and solve for H3O+.

pH = -log[H3O+]

<u>[H3O+] = 1.0*10^-12 M</u>

Now, to find the hydroxide ion concentration we will use the two following equations.

14 = pH + pOH

pOH = -log[OH-]

14 = 12 + pOH

pOH = 2

2 = -log[OH-]

<u>[OH-] = 0.01 M</u>
