A1.50 liter flask at a temperature of 25°c contains a mixture of 0.158 moles of methane, 0.09 moles of ethane, and 0.044 moles of butane. what is the total pressure of the mixture inside the flask?

The pressure of the mixture inside the flask is 4.76 atm

Explanation:

To calculate the pressure, we use the equation given by ideal gas equation:

PV = nRT

where,

P = Pressure of the flask = ?

V = Volume of the flask = 1.50 L

n = Total number of moles = 0.158 + 0.09 + 0.044 = 0.292 moles

R = Gas constant =

T = Temperature of the flask =

Putting values in above equation, we get:

Hence, the pressure of the mixture inside the flask is 4.76 atm

answer; i believe that the correct answer is (a) potassium(k)
