Answer:
Explanation:
To calculate the number of moles of gas that occupy a given volume at a certain pressure and temperature, we can use the ideal gas law equation: PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.
Given:
Pressure (P) = 2.3 ATM
Volume (V) = 120 L
Temperature (T) = 340 K
We can rearrange the ideal gas law equation to solve for the number of moles (n):
n = PV / RT
Plugging in the values:
n = (2.3 ATM 120 L) / (0.0821 LATM/molK 340 K)
n = 276 / 27.914
n ≈ 9.89 moles
Therefore, the number of moles of gas that occupy 120 L at a pressure of 2.3 ATM and a temperature of 340 K is approximately 9.89 moles.
try remember this ok??
