Solution Steps

Step 1: Identify the Ideal Gas Law

The Ideal Gas Law is given by the equation: PV=nRT PV = nRT where:

  • P P is the pressure,
  • V V is the volume,
  • n n is the number of moles,
  • R R is the ideal gas constant,
  • T T is the temperature in Kelvin.
Step 2: Assign Given Values

From the problem, we have:

  • n=0.627 n = 0.627 mol,
  • P=1.06 P = 1.06 atm,
  • T=287 T = 287 K.

The ideal gas constant R R is 0.0821 0.0821 L·atm/(mol·K).

Step 3: Rearrange the Ideal Gas Law to Solve for Volume

Rearrange the equation to solve for V V : V=nRTP V = \frac{nRT}{P}

Step 4: Substitute the Given Values into the Equation

Substitute the values into the equation: V=(0.627mol)(0.0821L\cdotpatm/(mol\cdotpK))(287K)1.06atm V = \frac{(0.627 \, \text{mol}) (0.0821 \, \text{L·atm/(mol·K)}) (287 \, \text{K})}{1.06 \, \text{atm}}

Step 5: Calculate the Volume

Perform the calculation: V=(0.627)(0.0821)(287)1.06 V = \frac{(0.627) (0.0821) (287)}{1.06} V=14.73571.06 V = \frac{14.7357}{1.06} V13.9007L V \approx 13.9007 \, \text{L}

Final Answer

The volume occupied by 0.627 mol of nitrogen gas at a pressure of 1.06 atm and a temperature of 287 K is: 13.9007L \boxed{13.9007 \, \text{L}}
