It depends on what type of graph you have. The easiest would be using a H-T diagram. Enthalpy of vaporization is the physical change from liquid to vapor. It occurs at a constant pressure and a constant temperature. As shown in the picture, 1 point is drawn on the subcooled liquid, and another point of the saturated vapor isothermal line. Now, the difference between those two points is the value for the enthalpy of vaporization of water.
Answer:
(a)
(b) Rubidium
Explanation:
Hello,
This titration is carried out by assuming that the volume of base doesn't have a significant change when the mass is added, thus, we state the following data a apply the down below formula to compute the molarity of the base solution:
Solving for the molarity of base we've got:
Now, we can compute the moles of the base as:
(a) Now, one divides the provided mass over the previously computed moles to get the molecular mass of the unknown base:
(b) Subtracting the atomic mass of oxygen and hydrogen, the metal's atomic mass turns out into:
So, that atomic mass dovetails to the Rubidium's atomic mass.
Best regards.
