| What is the
volume that 500 g of iodine will occupy under the conditions: |
|
| Temp = 300oC
and Pressure = 740 mm Hg? |

|
| Step 1) Write down given information. |
|||||
| mass
= 500 g iodine |
|||||
| T
= 300oC |
|||||
| P
= 740 mm Hg |
|||||
| R
= 0.0821 atm . L / mol . K |
|||||
| Step 2) Equation: |
| PV =
nRT |
| Step 3) Solve for variable |
| nRT |
| V |
| = |
| P |
| Step 4) Substitute in numbers and solve |
| (500 g)(0.0821 atm
. L / mol . K)(300oC) |
| = |
| V |
| 740 mm Hg |
| V = |
