Answer: 6.022x10²³ (Avogadro's Number)
Explanation: The number of particles in 1 mole of a substance is determined by the Avogadro's Number.
The concentration refers to the amount of substance that is contained in solution.
<h3>What is the concentration?</h3>
The concentration refers to the amount of substance that is contained in solution. We can be able to obtain the concentration of the raw acid by the use of the relation;
Co = 10pd/M
M = molar mass of the acid
p = percentage of the acid
d = density of the acid
Co = 10 * 36 * 1.18/36.5
Co = 11.6 M
Using the dilution formula;
C1V1 = C2V2
10 * 11.6 = C2 * 1000
C2 = 10 * 11.6/1000
C2 = 0.116 M
Using again;
C1V1 = C2V2
0.116 * 5 = C2 * 20
C2 = 0.116 * 5 /20
C2 = 0.029 M

A. -20kj
Explanation:
The reaction is exothermic
therefore enthalpy = 20 - 40 = -20
The partial pressure of the gas will be the total pressure minus the vapor pressure. 523.8-23.8=500mmHg. This makes sense due to the fact that the idea of partial pressures still works even with vapor pressure since vapor pressure is just the partial pressure of water vapor (23.8mmHg) in the container which is added to the partial pressure of hydrogen gas (500mmHg) to make a total pressure of 523.8mmHg.
I hope this helps. Let me know in the comments if anything is unclear.
