Question

Calculate the volume occupied by 2.0 moles of an ideal gas at 25°C and 380 mmHg.

a) 50 L
b) 0.05 L
c) 20 L
d) 10 L

Answer 1

To calculate the volume occupied by 2.0 moles of an ideal gas at 25°C and 380 mmHg, you can use the ideal gas law equation.

Step-by-step explanation:

To calculate the volume occupied by 2.0 moles of an ideal gas, we can use the ideal gas law equation:

V = (nRT)/P

Where V is the volume, n is the number of moles, R is the ideal gas constant, T is the temperature in Kelvin, and P is the pressure.

First, convert the temperature from Celsius to Kelvin by adding 273.15:

T = 25 + 273.15 = 298.15 K

Next, substitute the values into the ideal gas law equation:

V = (2.0 mol * 0.0821 L·atm/(mol·K) * 298.15 K) / 380 mmHg

Solving the equation gives:

V = 1.62 L

Therefore, the volume occupied by 2.0 moles of an ideal gas at 25°C and 380 mmHg is approximately 1.62 liters.
