Question

What is the temperature in °C of a 2.4g sample of C2H6 confined in a 0.300L bulb at a pressure of 209.3kPa?

A. -178.53 °C
B. 178.53 °C
C. 0 °C
D. 100 °C

Answer 1

To find the temperature of the sample, use the ideal gas law equation P × V = 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.

Step-by-step explanation:

To find the temperature of the sample, we can use the ideal gas law equation P × V = 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. Rearranging the equation, we have T = (P × V) / (n × R).

Firstly, we need to calculate the number of moles using the molar mass of C2H6 and the mass of the sample. Then, we can substitute the values into the equation to find the temperature in Kelvin. To find the temperature of the sample, use the ideal gas law equation P × V = 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.
