| 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 |
|||||
| n
= 1.9685 mol I2 |
|||||
| T = 573 K (300oC) |
|||||
| P = 0.9737 atm (740 mm Hg) |
|||||
| R = 0.0821 atm . L / mol .
K |
|||||
| V = ? L |
|||||
| Step 2) Equation:
PV = nRT |
| Step 3) Solve for variable |
| nRT |
| V |
| = |
| P |
| Step 4) Substitute in numbers and solve |
| (1.9685 mol)(0.0821 atm .
L / mol . K)(573 K) |
| = |
| V |
| 0.9737 atm |
| V = 95.1 L I2 |
