What is the pressure of the sample?

Question

A student has a sample of 1.66 moles of fluorine gas that is contained in a 27.7 L container at 297 K. What is the pressure of the sample? The ideal gas constant is 0.0821 L*atm/mol*K. Please round the answer to the nearest 0.01 and include units

Answer 1

This question requires that you use the ideal gas law which is formulated as PV=nRT. The variables given to you in the question are as follows:

P=?

V=27.7 L

n=1.66 mol

R= .0821 L*atm/mol*K

T=297 K

Plugging those into the equation gives P(27.7 L)=(1.66 mol)(.0821 L*atm/mol*K)(297K). Solving for P gives the equation P=(1.66 mol)(.0821 L*atm/mol*K)(297K)/ (27.7 L)= 1.46 atm
