Solving Ideal Gas Law Problem: Volume of Rigid Container at 1.20 atm and 60.0°C

[BryceHarper]

Homework Statement

A rigid container holds 2.80 mol of gas at a pressure of 1.20 atm and a temperature of 60.0 degrees Celsius. What is the container's volume?

Homework Equations

PV=nRT

The Attempt at a Solution

(2.80*8.31*333)/1.20 = 6457m^3

This answer seems way too big, what am I doing wrong?

Watch units.

 

[BryceHarper]

Should use N/m^2 rather than atm?

 

[BryceHarper]

Should I**

 

[TSny]

When you write 8.31 for R, what are the units that go with that number?

 

[BryceHarper]

J/mol*K

 

[TSny]

What system of units uses Joules, moles, and Kelvins? Then decide what the units of pressure are for that system of units.

Ahhhh okay, I got it now. Thanks!
