Answer:
Approximately 100 °C.
Explanation:
Hello,
In this case, since the entropy of vaporization is computed in terms of the heat of vaporization and the temperature as:
We can solve for the temperature as follows:
Thus, with the proper units, we obtain:
Hence, answer is approximately 100 °C.
Best regards.
Answer:
5 000 000 (5 million atoms)
Explanation:
Let us assume that a vanadium atom has a spherical shape.
diameter of a sphere = 2 x radius of the sphere
Thus,
Radius of a vanadium atom = 130 pm
= 130 x m
The diameter of a vanadium atom = 2 x radius
= 2 x 130 x
= 260 x m
Given a distance of 1.30 mm = 1.30 x m,
The number of vanadium atoms required to span the distance =
= 5000000
Therefore, the number of vanadium atom that would span a distance of 1.30 mm is 5 million.
