Answer:
21418100
Explanation:
2.14181 are remove point then give 14181/100000 then 10^7= 10000000 and solve it 14181/100000*10000000
<span>the pH of a 0.050 M triethylamine, is 11.70
</span>
For triehtylamine,
, the reaction will be
and we know, pH = -log[H+] and pOH = -log[OH-]
Also, pOH + pH = 14
Now, the Kb value = 5.3 x 10^-4
And
thus, [OH-] =(5.3 ^ 10-4) ^2 / 0.050
=0.00516 M
Thus, pOH = 2.30
pH = 14 - pOH = 11.7
The mass lost in the process is 1.4 * 10^-5Kg.
<h3>What is the Einstein equation?</h3>
The Einstein equation is able to relate the mass lost to the energy that is evolved in a nuclear process.
Given that;
E = Δmc^2
Δm = E/c^2
Δm = 1.26 × 10^12 J/( 3 * 10^8)^2
Δm = 1.4 * 10^-5Kg
