Answer:
Explanation:
Hello,
In this case, by knowing that the used NaOH equals in moles the acid (monoprotic) as shown below, during the titration:
By knowing the volume and the concentration of the NaOH, one obtains:
Thus, the molar mass of the acid is computed based on the previously computed moles and the given mass as follows:
Best regards.
I know that we can find how old the Earth is by knowing how much uranium ultimately decayed into lead. Uranium-238 has a very long to decay, about 4.5 billion years. So that is how we are able to understand how old the Earth is.
Answer:
Neutrons or Neutral atoms
