This is called the Mass Number of the isotope of the atom.

Isotopes are different forms of the same atom. They have the same number of protons  but different number of neutrons.

Carbon-12 has mass number  12 as it has 6 protons and 6 neutrons.

Carbon-14 has mass number 14 as its has 6 protons and 8 neutrons.

What is the ph of a 0.006 m koh solution? 1. 11.78 2. 7.00 3. 2.22 4. 8.88 5. 5.12?
Stels [109]
The concentration of OH⁻ is first converted to pOH bu using followinf formula,

                                           pOH  =  -log [OH⁻]
Putting value,
                                           pOH  =  -log (0.006)

                                           pOH  =  2.221
As we know,
                                   pH + pOH  =  14
Solving for pH,
                                   pH  =  14 - pOH
Putting value of pOH,
                                   pH  =  14 - 2.221

                                   pH  =  11.779
Result:
           Option-1
is the correct answer.
