Question

The volume noted in the figure contains nitrogen gas under a pressure of 2.3 atm at 25°C. Calculate the number of moles of nitrogen in the tank.

A. 0.060 moles
B. 0.095 moles
C. 0.124 moles
D. 0.150 moles

Answer 1

Without knowing the volume, we cannot calculate the number of moles of nitrogen.

Step-by-step explanation:

To calculate the number of moles of nitrogen gas in the tank, 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.

In this case, we are given the pressure (2.3 atm), volume (not provided), and temperature (25°C). We need to convert the temperature to Kelvin by adding 273.15 to it (25°C + 273.15 = 298.15 K).

Without knowing the volume, we cannot calculate the number of moles of nitrogen. Therefore, the answer cannot be determined with the given information.
