Answer:
23.76g
Explanation:
To solve for the mass of carbon dioxide (CO2), let us first obtain the number of mole of CO2.
From the question, the following were obtained:
V = 8.13L
P = 204kPa = 204000Pa
Recall: 101325Pa = 1atm
204000Pa = 204000/101325 = 2atm
T = 95°C = 95 + 273 = 368K
R = 0.082atm.L/K/mol
n =?
PV = nRT
n = PV /RT
n = 2 x 8.13/ 0.082 x 368
n = 0.54mole
Now let us convert 0.54mole of CO2 to gram. This is illustrated below:
Molar Mass of CO2 = 12 + (16x2) = 12 + 32 = 44g/mol
Number of mole of CO2 = 0.54mole
Mass of CO2 =?
Number of mole = Mass /Molar Mass
Mass = number of mole x molar Mass
Mass of CO2 = 0.54 x 44
Mass of CO2 = 23.76g

Explanation: Because is the only that makes sense and the only one that seems right
Answer: 1.11 atm
Explanation:
The unit of pressure include kilopascal (kPa), atmospheres (atm), mmHg etc
Now, given that:
Air pressure = 113 KPa
Convert kPa to atm
If 101.325 kPa = 1 atm
113 kPa = Z atm
To get the value of Z, cross multiply
Z atm x 101.325 kPa = 1 atm x 113 kPa
Z = ( 1 atm x 113 kPa) / 101.325 kPa
Z = 1.11 atm
Thus, the pressure is 1.11 atm
