Expert Answer
Ideal Gas law
PV = nRT
n = number of moles
R = universal gas constant = 8.3145 J/mol K
PV = nRT
n = number of moles
R = universal gas constant = 8.3145 J/mol K
Boyle's law
P1V1 = P2V2
P1V1 = P2V2
Gay-Lussac law
| P1 | = | P2 |
| T1 | T2 |
Combined Gas law
| P1V1 | = | P2V2 |
| T1 | T2 |
Charles law
| V1 | = | V2 |
| T1 | T2 |
Concentration is the ratio of solute and solvent.
Concentration can be measured using molarity, molality and mole fraction.
Concentration can be measured using molarity, molality and mole fraction.
| Molarity (M) = | moles of solute |
| liters of solution |
| Molality (m) = | moles of solute |
| kg of solution |
| Mole-fraction (Xa)= | molesa |
| molesa + molesb .... |
One mole of gas has volume of 22.4 liter at STP.
