Sagot :
Answer:
I took the test, see below
Explanation:
1. The volume increases to twice its original value.
2. volume & temperature are directly proportional
volume & pressure are inversely proportional
pressure & temperature are directly proportional
3. Gay-Lussac’s law, by seeing how changes in temperature affect the pressure of the gas
4.V1P1/T1=V2P2/T2
5. It is a straight line with a positive slope showing that an increase in temperature results in an increase in volume.
6. keeping the pressure constant and increasing the temperature
7. When temperature is held constant and volume increases, the pressure increases.
8. pressure, volume, temperature, number of moles
9. volume
10. 7.10 L/mol
11. 0.105 mol
12. 27 g/mol
13. the temperature increasing by a factor of 2
The rest are short answers, just give those your best shot.
The molar mass of the gas in grams per mole is 27 g/mol
The correct answer to the question is Option D. 27 g/mol
To solve this question, we'll begin by calculating the number of mole of the gas. This can be obtained as follow:
Temperature (T) = 280 K
Pressure (P) = 0.95 atm
Volume (V) = 4.92 L
Gas constant (R) = 0.0821 L⋅atm/mol⋅K
Number of mole (n) =?
PV = nRT
0.95 × 4.92 = n × 0.0821 × 280
4.674 = n × 22.988
Divide both side by 22.988
n = 4.674 / 22.988
n = 0.203 mole
Thus, the number of mole of the gas is 0.203 mole.
Finally, we shall determine the molar mass of the gas. This can be obtained as follow:
Number of mole of gas = 0.203 mole.
Mass of gas = 5.49 g
Molar mass =?
Mole = mass / molar mass
0.203 = 5.49 / molar mass
Cross multiply
0.203 × molar mass = 5.49
Divide both side by 0.203
Molar mass = 5.49 / 0.203
Molar mass = 27 g/mol
Therefore, the molar mass of the gas is 27 g/mol
Option D. 27 g/mol gives the correct answer to the question.
