The choices are not given, however, the question can still be solved.

<u>We know that:</u>
pH + pOH = 14
<u>Converting the above equation to concentration form, we will get:</u>
[H₃O+] * [OH-] = 10⁻¹⁴

<u>We are given that:</u>
concentration of hydroxide ion [OH-] = 1.4 * 10⁻¹⁰ M

<u>Substitute with this in the above equation to get concentration of hydronium ion as follows:</u>
[H₃O+] * [OH-] = 10⁻¹⁴
[H₃O+] * [1.4 * 10⁻¹⁰ ] = 10⁻¹⁴
[H₃O+] = \frac{10^{-14} }{1.4* 10^{-10} }
[H₃O+] = 7.1428 * 10⁻⁵ M

Hope this helps :)

Jones Co. pays its employees on a graduated commission scale: 2% on first $30,000; 3% on sales from $30,000 to $60,000; and 5% o
Gnesinka [82]
We need to separate his total earnings out into the different categories:

Category 1 (2%): 30,000
Category 2 (3%): 60,000-30,000 = 30,000
Category 3 (5%): 92,000-60,000 = 32,000

To calculate a percentage we multiply by that percentage divided by 100.
Now we can work out the commissions:
1) 30,000*0.02 = $600
2) 30,000*0.03 = $900
3) 32,000*0.05 = $1600

Adding these together, we get $3100
