I have value for frequency and inductance, need to find out the value of the capacitor.

Assuming that f is the resonant frequency:
(2*pi*f)^2 = 1/(L*C)
f=frequency in Hz
pi=3.1415926535.....
L=inductance in Henries
C=capacitance in Farads
...do an elementary rearrangement of the initial equation (solve for C) and you will have your answer ;)
I don't like to do math for people because there are too many people on here looking for free homework help, but you can see that if you multiply both sides by C/(2*pi*f)^2 you will solve for C in one step rather than all of the monkey business in the other post.

Your probably referring to a circuit in resonance effect where the inductance and capacitive reacances are equal. if this is the case then,
w=sqrt(1/LC)
since w=2*pi*f
2*pi*f=sqrt(1/LC) square both sides
(2*pi*f)^2=1/LC multiply both sides by L
L*(2*pi*f)^2=1/C invert both sides
C=1/(L*(2*pi*f)^2
