Question

What is the pressure (P) in the ideal gas law equation when:

T = 350 K, V = 9 L, n = 50 moles, R = 8 L·kPa/(mol·K)?

A) P ≈ 15,555.56 kPa

B) P ≈ 1,555.56 kPa

C) P ≈ 155,555.56 kPa

D) P ≈ 155.56 kPa

Answer 1

Using the ideal gas law formula PV = nRT and the values provided, the pressure (P) is found to be approximately 155,555.56 kPa, which corresponds to choice C.

Step-by-step explanation:

To find the pressure (P) in the ideal gas law equation, you can use the formula PV = nRT.

Given the values:

• Temperature (T) = 350 K
• Volume (V) = 9 L
• Number of moles (n) = 50 moles
• Gas constant (R) = 8 L·kPa/(mol·K)

You can rearrange the ideal gas law to solve for P:

P = (nRT)/V

Plugging in the values we get:

P = (50 moles * 8 L·kPa/(mol·K) * 350 K) / 9 L

P ≈ 155,555.56 kPa

Therefore, the correct choice is C) P ≈ 155,555.56 kPa.
