AN OBJECT FLOAT BECAUSE OF ITS LOW CAPACITY AND SINKS BECAUSE OF ITS HIGH CAPACITY
Answer:
energy = 391.902 kJ /mol
Explanation:
given data
wavelength = 305 nm = 305 ×
m
to find out
average energy
solution
we know speed of light is 3 ×
m/s
so we find frequency here first by speed of light formyla
speed = wavelength × frequency
3 ×
= 305 ×
× frequency
frequency = 9.8360 ×
so energy is
energy = hf
here h = 6.62 ×
J-s
so
energy = 6.62 ×
× 9.8360 ×
energy = 6.51 ×
J
so
energy = 6.51 ×
×
kJ/mol
energy = 391.902 kJ /mol
V = 174 m/s
