Question

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

Answer 1

57 L

Step-by-step 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 * (1atm)/(760torr) = 0.987atm`

Step 3: Calculate the volume of the Ne sample

We will use the ideal gas equation.

`P * V = n * R * T\\V = (n * R * T)/(P) \\V = (2.3mol * (0.0821atm.L)/(mol.K) * 300K)/(0.987atm)\\V = 57 L`
