Dalam ruangan tertentu terdapat 0,1 mol gas NO yang mempunyai tekanan 2 atmosfer dan temperatur 27°C. Volume gas NO dalam ruangan tersebut adalah …. ( Ar N=14,0 , O=16, R=0,082 L atm/mol K)

Dalam ruangan tertentu terdapat 0,1 mol gas NO yang mempunyai tekanan 2 atmosfer dan temperatur 27°C. Volume gas NO dalam ruangan tersebut adalah …. ( Ar N=14,0 , O=16, R=0,082 L atm/mol K)

Jawaban: Volume gas NO adalah 1,23 L

Volume gas pada suhu dan tekanan tertentu dapat ditentukan dengan persamaan gas ideal. Persamaan gas ideal merupakan pendekatan untuk mengkarakterisasi gas pada keadaan tertentu.
P x V = n x R x T
P = tekanan (atm)
V = volume (L)
n = mol
R = tetapan gas ideal (0,082 atm L/mol K)
T = temperatur (K)

Gas NO memiliki tekanan 2 atm dan suhu 27 °C. Suhu tersebut harus dikonversi menjadi satuan Kelvin.
T = (27 + 273) K = 300 K

Volume NO adalah:
P x V = n x R x T
2 atm x V = 0,1 mol x 0,082 atm L/mol K x 300 K
V = 1,23 L

Jadi, volume gas NO adalah 1,23 L.
