Mol = Mol
1,2044.10²³
b) P = 1atm T= 25+273
P.V = n . r .T
1 . V = 0,2 . 0,082 . 298
V=4,8872 L
c) P = 2 atm T = 30 +273
P.V = n . R . T
2 . V = 0,2 . 0,082 . 303
V = 2,4846L
Bener kan?
Mr NO2 = 46
Ditanya: a. Mol NO2?
b. Volume gas NO2 (keadaan STP)?
c. Volume gas NO2 (P= 2 atm, T=30⁰C)
Jawab:
a. Mol NO2 = massa÷Mr
= 9,2 gr÷46
= 0,2
b. Volume gas NO2 (STP) = mol×22,4
= 0,2×22,4
= 4,48 liter
c. Volume gas NO2 :
P.V=n.R.T
2.V=0,2.0,082.(30+273)
2V=4,9692
V=2,4846 liter
Smoga mmbntu.., :-)
