Answer:

Option D. atm, L, K, mole

Step-by-step explanation:

To know which option is correct, do the following:

We shall use the standard value for each variable to obtain the gas constant. This can be obtained as follow:

Volume (V) = 22400 mL

Pressure (P) = 760 mmHg

Number of mole (n) = 1 mole

Temperature (T) = 273 K

Gas constant (R) =?

PV = nRT

R = PV / nT

R = (760 × 22400) / (1 × 273)

R = 62358.97 mmHg.mL/Kmol

Volume (V) = 22.4 L

Pressure (P) = 760 mmHg

Number of mole (n) = 1 mole

Temperature (T) = 273 K

Gas constant (R) =?

PV = nRT

R = PV / nT

R = (760 × 22.4) / (1 × 273)

R = 62.359 mmHg.L/Kmol

Volume (V) = 22400 mL

Pressure (P) = 1 atm

Number of mole (n) = 1 mole

Temperature (T) = 273 K

Gas constant (R) =?

PV = nRT

R = PV / nT

R = (1 × 22400) / (1 × 273)

R = 82.05 atm.mL/Kmol

Volume (V) = 22.4 L

Pressure (P) = 1 atm

Number of mole (n) = 1 mole

Temperature (T) = 273 K

Gas constant (R) =?

PV = nRT

R = PV / nT

R = (1 × 22.4) / (1 × 273)

R = 0.0821 atm.L/Kmol

From the above illustrations, we can see that the gas constant will have a value for 0.0821 as long as other variables are: atm, L, K, mole
