Some Useful Equations & Conversions

cylinder = (p) r²h
sphere = 4/3 (p) r³ = 4.189 r³

cylinder = 2 (p) r² + 2 (p) rh
sphere = 4(p)r² = 12.57r²
circle = (p)r²

Molarity = mol liter^-1
Molality = 1000 g liter^-1
c₁ v₁ = c₂ v₂
formula weight = g mol^-1
% = grams/volume* 100

1 mm³ = 1 �L  =  1000 nL = 1 x 10^-6 pL
1 cm³ = 1 mL
1 �m³ = 10^-9 mm³ = 10^-9  �L = 10^-6 nL = 10^-3 pL
