To find the average kinetic energy per molecule of helium gas, we can use the equation:

Average kinetic energy per molecule = (3/2) * k * T

where:
- k is Boltzmann's constant (1.38 × 10^-23 J/K)
- T is the temperature in Kelvin

First, we need to convert the given temperature from Celsius to Kelvin:

T(K) = T(°C) + 273.15
T(K) = 176 °C + 273.15
T(K) = 449.15 K

Now that we have the temperature in Kelvin, we can substitute the values into the equation:

Average kinetic energy per molecule = (3/2) * (1.38 × 10^-23 J/K) * 449.15 K

Calculating the expression:

Average kinetic energy per molecule = (3/2) * (1.38 × 10^-23 J/K) * 449.15 K
Average kinetic energy per molecule ≈ 9.19 × 10^-21 J

Therefore, the average kinetic energy per molecule of helium gas is approximately 9.19 × 10^-21 J.
