Diket: massa gas (m) = 975 gram = 0,975 kg Suhu ( T ) = 600 K Volume (V) = 600 liter = 0,6 m^3 Tekanan (P) = 5 atm = 5 x 10^5 pa R = 8,314 J/molK (tetapan umum gas) Ditanya: Massa molekul relatif (Mr)............?
Jawab: n = P.V/RT n = 5x10^5 . 0,6 / 8,314 x 600 n = 3x10^5 / 4988,4 n = 60
Mr = massa/n Mr = 0,975/60 Mr = 0,01625 kg atau Mr = 16,25 gram
m = 975 gr
V = 600 L
P = 5 atm
T = 600 K
Ditannya
Mr=___?
Jawab
massa gas (m) = 975 gram = 0,975 kg
Suhu ( T ) = 600 K
Volume (V) = 600 liter = 0,6 m^3
Tekanan (P) = 5 atm = 5 x 10^5 pa
R = 8,314 J/molK (tetapan umum gas)
Ditanya: Massa molekul relatif (Mr)............?
Jawab:
n = P.V/RT
n = 5x10^5 . 0,6 / 8,314 x 600
n = 3x10^5 / 4988,4
n = 60
Mr = massa/n
Mr = 0,975/60
Mr = 0,01625 kg
atau Mr = 16,25 gram
