<u>Answer:</u> The number of moles of nitrogen gas are 0.1043 moles and the pressure when volume and temperature has changed is 461.6 mmHg
<u>Explanation:</u>
To calculate the amount of nitrogen gas, we use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 755 mmHg
V = Volume of the gas = 2.55 L
T = Temperature of the gas =
R = Gas constant =
n = number of moles of nitrogen gas = ?
Putting values in above equation, we get:
To calculate the pressure when temperature and volume has changed, we use the equation given by combined gas law.
The equation follows:
where,
are the initial pressure, volume and temperature of the gas
are the final pressure, volume and temperature of the gas
We are given:
Putting values in above equation, we get:
Hence, the number of moles of nitrogen gas are 0.1043 moles and the pressure when volume and temperature has changed is 461.6 mmHg
Answer:
The answer to the question is;
The occupant load of the store having a floor area of 100,000 ft² is 3,317.86 persons.
Explanation:
Based on NFPA guidelines we have for sales on street floor, the allowable occupant load factor per person is 30 ft²
That is where the floor area is 100,000 square feet we have the number of allowable occupant given by
(100,000 ft²)/(30 ft²/Person) = or 3,333 persons
That is the occupant load of the store if the floor area is 100,000 square feet = 3,333 persons
Based on m² we have 9,290 m² will require 2.8 m²/person
which gives;
(9,290 m²)/(2.8 m²/person) = = 23225/7 or 3,317.86 persons
Therefore applying safety, we go with the lesser number and we have
The occupant load of the store having a floor area of 9,290 m² = 3,317.86 persons.
