Question

At 27 C and 750 torr pressure, what will be the volume of 2.3 mol of Ne?

Answer 1

Answer:

57 L

Explanation:

Step 1: Convert the temperature to Kelvin

When working with gases, we always use the absolute temperature scale.

$K = \°C + 273.15\\K = 27 + 273.15\\K = 300 K$

Step 2: Convert the pressure to atmospheres

$750 torr \times \frac{1atm}{760torr} = 0.987atm$

Step 3: Calculate the volume of the Ne sample

We will use the ideal gas equation.

$P \times V = n \times R \times T\\V = \frac{n \times R \times T}{P} \\V = \frac{2.3mol \times \frac{0.0821atm.L}{mol.K} \times 300K}{0.987atm}\\V = 57 L$
