Lakukan tugas rumah & ujian kamu dengan baik sekarang menggunakan Quizwiz!
Molality differs from molarity because it involves...
temperature
Henrys law
Sg=kPg
Percentage weight
(G of solute/ g solute +g solvent) x 100
"k" in Henrys law
Constant
Mass percentage
Mass of component in soln/ total mass of soln x 100
Mole fraction
Mole of components/ total moles
Molality (m)
Moles of solute/kg solvent
Molarity(M)
Moles of solute/liter of soln
"P" in Henrys Law
Partial pressure
Ppb
Parts per billion 10^9
Ppm
Parts per million 10^6
"Sg" in Henrys law
Solubility of gas (Molarity)
Molarity Def.
The concentration of a solution given in grams of solute per liter of solution.
Molality Def.
The number of of solute divided by the number of of solvent
Grams to moles
g/mm=moles
