Equations

Question 1

Henry’s Law: Solubility of Gases w/ Increasing Pressure

Answer 1

S_gas= k_HP_gas

S=solubility

k_H=Henry’s Constant

Question 2

Molarity (M)

Answer 2

number of moles ÷ volume in L

Question 3

Molality (m)

Answer 3

number of moles/mass(kg)

mol/kg

Question 4

Concentration of a Solution in Mole Fraction (X)

Answer 4

(n_solute)/(n_solute+n_solvent)

Question 5

Mol %

Answer 5

Mol % = X * 100%

Question 6

Raoult’s Law: Relationship btwn Vapor Pressure of a Solution, the Mole Fraction of the Solvent, and the Vapor Pressure of the Pure Solvent.

Answer 6

P_solution=X_solvent+P_solvent

Question 7

Relationship btwn the Freezing Point Depression, Molality, and Freezing Point Depression Constant.

Answer 7

∆T_f = m * Kf

Question 8

Relationship btwn the Boiling Point Elevation, Molality, and Boiling Point Elevation Constant.

Answer 8

∆T_b = m * K_b

Question 9

Relationship btwn Osmotic Pressure, Molarity, the Ideal Gas Constant, and Temperature.

Answer 9

Π=MRiT

Question 10

Different Ideal Gas Constants

Answer 10

8. 314 J /K *mol
9. 08206 L*atm/(K*mol)
