Question

Calculate the approximate volume of a 0.600 mol sample of gas at 15.0ºC and a pressure of 0.63 atm.

Answer 1

Answer:

the approximate volume of the gas sample at 15.0ºC and 0.63 atm pressure is 14.9 L.

Step by step explanation:

To calculate the volume of a gas sample, we can use the Ideal Gas Law:

PV = nRT

where P is the pressure in atmospheres, V is the volume in liters, n is the number of moles, R is the gas constant (0.08206 L·atm/K·mol), and T is the temperature in Kelvin.

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

T = 15.0ºC + 273.15 = 288.15 K

Next, we can plug in the values and solve for V:

V = (nRT) / P

V = (0.600 mol)(0.08206 L·atm/K·mol)(288.15 K) / (0.63 atm)

V ≈ 14.9 L

Therefore, the approximate volume of the gas sample at 15.0ºC and 0.63 atm pressure is 14.9 L.

Answer 2

The approximate volume of the gas is 14.8 L.

Step-by-step explanation:

To calculate the approximate volume of the gas, we can use the Ideal Gas Law, which relates the pressure, volume, temperature, and number of moles of a gas:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant (0.08206 L·atm/(mol·K)), and T is the temperature in Kelvin.

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

T = 15.0ºC + 273.15 = 288.15 K

Then, we can rearrange the Ideal Gas Law to solve for the volume:

V = (nRT) / P

Plugging in the given values:

V = (0.600 mol)(0.08206 L·atm/(mol·K))(288.15 K) / 0.63 atm

V ≈ 14.8 L

Therefore, the approximate volume of the gas is 14.8 L.
