The mass fraction of the hydrogen atom is 0.9995 u.
<h3>Calculation:</h3>
We know that mass fraction can be determines as,
Mass fraction = Mass of proton/mass of H atom
Given,
Mass of proton = 1.007276 u
Mass of H atom = 1.007825 u
Put the values in the formula,
Mass fraction = Mass of proton/mass of H atom
Mass fraction = 1.007276/1.007825
= 0.9995 u
Hence, the mass fraction of the hydrogen atom is 0.9995 u.

<h3>ir id n becuswe ig gyst makres sensre</h3>
Explanation:
Answer: The question has some details missing. Here is the complete question ; An molecule adsorbed at one site on a surface. An oxygen molecule is adsorbed onto a small patch of the surface of a catalyst. It's known that the molecule is adsorbed on 1 of 576 possible sites for adsorption (see sketch at right). Calculate the entropy of this system. Round your answer to 3 significant digits.
Explanation:
The stefan boltzmaan constant for entropy is given by ;
- we are given that 576 total possible sites in which O2 can get absorbed
- w = 576, k = 1.38 x 10-23J/k
plugging the values into the equation ;
S = 1.38 x 10-23J/k X In(576)
Entropy of the system = 8.79 X 10-23J/k
Answer:
Therefore the capacitance of the capacitor is 2.38 * 10⁻⁵F
Explanation:
We apply the concepts related to Power and energy stored in a capacitor.
By definition we know that power is represented as
Where,
E= Energy
t = time
to find the Energy we have,
With the energy found we can know calculate the Capacitance in a capacitor through the energy for capacitor equation, that is
Therefore the capacitance of the capacitor is 2.38 * 10⁻⁵F
