Pada keadaan normal (T=0°C dan p=1 atm) 0,4 gram gas oksigen O2 (Mr=32) memiliki volume sebesar ….. (R=8,314 J/k mol, 1 atm = 10³ N/m²) a. 1,4 x 10^-6 m³ b. 2,8 x 10^-4 m³ c. 22,4 x 10^-3 m³ d. 2,8 m³ e. 22,4 m³
tuanpenanya Diketahui : m = 4 gram = 4 x 10-3 kg T = ( 0 + 273 ) K = 273 K P = 1 atm = 105 N/m2 M = 32 kg/kmol Ditanya : V = ..................? Jawab : pV = m RT/ M V = mRT/pM V = (4 x 10-3 kg) (8.314 J/kmol K) (273 K )/(105 N / m2 ) ( 32 kg / kmol ) V= 9078888 x 10-3/ 3200000 = = 2,8 x 10-3 m3
T = ( 0 + 273 ) K = 273 K
P = 1 atm = 105 N/m2
M = 32 kg/kmol
Ditanya : V = ..................?
Jawab : pV = m RT/ M
V = mRT/ pM
V = (4 x 10-3 kg) (8.314 J/kmol K) (273 K )/(105 N / m2 ) ( 32 kg / kmol )
V= 9078888 x 10-3/ 3200000
= = 2,8 x 10-3 m3
