The total pressure of the gas, in kPa is equal to 102.4 kPa.
Given the following data:
- Atmospheric pressure = 100.8 kPa
- Pressure (open side) = 12 mm Hg
To determine the total pressure of the gas, in kPa:
First of all, we would convert the value of the pressure in mm Hg to kPa.
Conversion:
760 mm Hg = 101.325 kPa
12 mm Hg = X kPa
Cross-multiplying, we have:
X = 1.60 kPa
Now, we can calculate the total pressure by using this formula:
Total pressure = 102.4 kPa

Answer:
102kPa
Explanation:
760mmHg = 101.325 kPa
12mmHg = x
Upon converting from mmHg to kPa we have;
x = ( 12 mm Hg x 101.325 kPa) / 760mmHg
x = 1.599868421 kPa
Total pressure = 100.8 kPa + 1.599868421 kPa
Total pressure = 102kPa

Answer:
NF3< H2S< H2O< He
Explanation:
The average speed of a gas depends on the relative molecular mass of the gas. Lighter gases have a greater average speed and move faster than heavier gases.
Hence, we need to arrange these gases listed in the question in order of decreasing molecular mass in order to obtain the order of increasing Urms assuming equivalent amounts and all gases are at the same temperature and pressure.
Hence; NF3< H2S< H2O< He
Final answer:
The rank in order of increasing Urms for the gases given, assuming the same amount, temperature, and pressure is as follows: NF₃, H₂S, H₂O, and He.
Explanation:
Urms, or root mean square speed, of a gas, depends on the molar mass of the gas and the temperature. It is determined by the formula Urms = sqrt(3kT/M), where k is Boltzmann's constant, T is temperature, and M is the molar mass. The greater the molar mass, the lower the Urms. Looking at the molar masses of the gases H₂S (34 g/mol), He (4 g/mol), NF₃(71 g/mol), and H₂O (18 g/mol), we can rank them in order of increasing Urms as NF₃ 1st), H₂S (2nd), H₂O (3rd), and He (4th).
