In experiment, the diameter of oil patch was 21 cm for an oil drop of radius 0.28 mm. determine the diameter of oil molecule
Volume of the oil patch = volume of oil drop
Volume of oil patch = ?pr?^(2 )×h
Where: h is the height of the oil molecule and is equal to the diameter of the oil molecule
R is the radius of the oil patch
Volume of oil drop = 4/3 ?pr?^3 where r is the radius of the oil drop
22/7 × ?0.105?^(2 )×h= 4/3 × 22/7 × ?0.000288?^3
h= ( 4/3 × 22/7 × ?0.000288?^3)/(22/7 × ?0.105?^(2 ) )
h= (3.0030467657142857142857142857143e-10)/0.03465
h= 2.8889338775510204081632653061224e-9 m
