Q

Fórmulas

A

C= v/l
/\E= Rh(1/n^2i + 1/n^2f) = hv
l = h/mv m = masa
E = hc/l
S= q/m /\T
q rxn = -Ccal /\T
q rxn/mol
MiVi = MfVf
Molaridad = moles de soluto/ litros de solución
Rendimiento real / rendimiento teórico x 100% = porcentaje de rendimiento
V1/T1 = V2/T2
P1V1/T1 = P2V2/T2
PV =nRT
Pa =naRT/V
Xa = moles a/moles totales
Pa = XaPtotal
