Hope it helps:D
When NH3 is dissolved in water, it dissociates partially producing NH4+ ions and OH- ions. It has an equation:
NH3 + H2O → NH4+ + OH-
<span>We use the Kb expression to determine the [OH-] concentration,
</span>
<span>Kb = [NH4+] [OH-] /* [NH3] </span>
We can write NH4+ as OH- since they are of equal ratio.
<span>(1.76*10^-5) = [OH-]² / 0.188
</span><span>[OH-]² = 3.3088*10^-6 </span>
<span>[OH-] = 1.819*10^-3 </span>
We calculate for H+ concentration as follows:
<span>[H+] [OH-] = 10^-14 </span>
<span>[H+] = 10^-14 / [OH-] </span>
<span>[H+] = 10^-14 / (1.819*10^-3) </span>
<span>[H+] = 5.50*10^-12 </span>
<span>pH = -log [H+] </span>
<span>pH = -log (5.5*10^-12) </span>
<span>pH = 11.26</span>
Silica content, temperature and gas content. The resistance and Heat are some of the things that control the viscosity of lava
The atomic mass of the elements is the weighted average of the masses of the isotopes.
This is, atomic mass = % of isotope 1 * mass number of isotope 1 + % of isotope 2 * mass number of isotope 2 + .... + % of isotpe 3 * mass number of isotope n.
Applied to our hypotethical element with 3 isotopes:
aomic mass of the element = 39.2 = 78.8% * 39 + 3.1% * 41 + 18.1% * x
Solve for x, x = [39.2 - 30.732 - 1.271] / .181 = 39.76 = 40
