The question is incomplete, here is the complete question:

A 5.00 L tank at 4.19°C is filled with 16.7 g of boron trifluoride gas and 9.15 g of chlorine pentafluoride gas. You can assume both gases behave as ideal gases under these conditions. Calculate the mole fraction and partial pressure of each gas, and the total pressure in the tank. Be sure your answers have the correct number of significant digits.

a. mole fraction of boron trifluoride:

b. partial pressure of boron trifluoride:

c. mole fraction of chlorine pentafluoride:

d. partial pressure of chlorine pentafluoride:

e. Total pressure in tank:

For a: Mole fraction of boron trifluoride is 0.778

For b: Partial pressure of boron trifluoride is 1.12 atm

For c: Mole fraction of chlorine pentafluoride is 0.222

For d: Partial pressure of chlorine pentafluoride is 0.320 atm

For e: Total pressure in tank is 1.44 atm

Explanation:

To calculate the number of moles, we use the equation:

     .....(1)

Given mass of boron trifluoride = 16.7 g

Molar mass of boron trifluoride = 67.8 g/mol

Putting values in equation 1, we get:

Given mass of chlorine pentafluoride = 9.15 g

Molar mass of chlorine pentafluoride = 130.5 g/mol

Putting values in equation 1, we get:

To calculate the pressure of the tank, we use the equation given by ideal gas which follows:

where,

P = pressure of the tank = ?

V = Volume of the tank = 5.00 L

T = Temperature of the gas =

R = Gas constant =

n = Total number of moles of the tank = [0.246 + 0.070] = 0.316 moles

Putting values in above equation, we get:

Mole fraction of a substance is given by:

    .......(2)

To calculate the partial pressure, we use the equation given by Raoult's law, which is:

     .....(3)

Moles of boron trifluoride = 0.246 moles

Total moles = 0.316 moles

Putting values in equation 2, we get:

We are given:

Putting values in equation 3, we get:

Moles of chlorine pentafluoride = 0.070 moles

Total moles = 0.316 moles

Putting values in equation 2, we get:

We are given:

Putting values in equation 3, we get:

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
