Equations I will give you on the test
| F = 1.8 (oC) + 32 |
oC= (F-32)/1.8 |
heat (cal) = g x oC x sp. heat (cal/goC) |
P1V1 = P2V2
T1n1 T2n2 |
STP conditions are:
Volume = 22.4 L
Temp = 273 K
Pressure = 1 atm
moles = 1 mole |
percent = mass (g) or volume (mL)
solutions 100 g or mL of solution
|
| Molarity (M) = moles/L |
Kw = [H3O+] [OH-]
Kw = (1 x 10-7) (1 x 10-7) |
pH = -log [H3O+] |
| M1V1 (initial) = M2V2 (final) |
