Molecular Formula
Glucose (a sugar)
Molecular Formula = C6H12O6
 6 atoms carbon, C
 12 atoms hydrogen, H
 6 atoms oxygen, O
Atomic mass
 The average mass of the atoms of an element as
they occur in nature
 Atomic mass units, amu
 1 amu = 1/12th the mass of one carbon-12 atom
 The mass of an electron is very small so more than
99
...
66 x 10–24 g (a very small number!)
 Symbol used in chemistry and Formula used in chemistry

 Symbol used in chemistry


d= density
v= volume
m= mass
Cp= specific heat
q= heat
ΔT= change in temperature
K= Kelvin
C= Celsius

 Formula used in chemistry


d=m/v
v=m/d

m=v*d
Cp= q/ (m* ΔT)
q= Cp*m*ΔT
ΔT= q/Cp*m
m= q/Cp* ΔT
Tf= q/m*Cp +Ti
Ti= q/m*Cp +Tf (then divide everything on the right by negative 1 [-1]) **this
formula isn't used as often as Tf**
t(C°)= T(K) - 273
...
1°C -- used to find Kelvin
