Solutions, Formulas
Ms. Singh's chpt. 10 formulas
| Question | Answer |
|---|---|
| M= (what's the formula) | Moles of sol/ liters of soln. |
| Moles of concentrated solution = ______________________ | moles of diluted solution |
| M^c x V^c = M^d x V^d, what can this formula be used to find? What do the variable stand for? | To find the moles in a soln. M: Molarity V: Volume in liters |
| What is the formula for Raoult's law? | delta P = X^2 x P^1 X: mole fraction |
| How do you find delta P in Raoult's law? | Final VP - initial VP |
| Henry's Law? | C^g = kP^g C^g: concentration of solution P^g: partial pressure of gas over solution k: constant found by dividing concentration of element/ 1 atm |
| Freezing Pt. Depression | Delta T^f = k^f OR delta T = Original freezing temp - new freezing temp |
| Boiling Point Elevation | Delta T^b = k^b OR delta T^b = Original boiling temp - new boiling temp |
| Osmotic pressure | (pie symbol) = MRT = nRT/V (pie symbol) IS ONLY A VARIABLE NOT 3.14… **** R: .0821 T: Temp in KELVIN M: Molarity |
| Molality | Moles of solute / kgs of solvent = m LOWERCASE "m" |
