Vo = [(rs+rf)/rs] * Vs.
Rs = 2.4k,
Rf = 120k,
Vs = 120 * 10^-6,
Vo = (2.4k + 120k)/2.4k,
Vo = 51 * 120 * 10^-6,
Vo = 6.12mV,
Rs = 2.4k,
Rf = 120k,
Vs = 120 * 10^-6,
Vo = (2.4k + 120k)/2.4k,
Vo = 51 * 120 * 10^-6,
Vo = 6.12mV,

Vo = (1 + Rf/R1)V1.
= (1 + 120/2.4) * 120.
= (1 + 50) * 120.
= 51 * 120.
= 6120 Micro V.
= 6.12 mV.
= (1 + 120/2.4) * 120.
= (1 + 50) * 120.
= 51 * 120.
= 6120 Micro V.
= 6.12 mV.

Can anyone explain the practical higher and lower limits for feedback resistor values in a non inverting amplifier?
i.e., Consider 1+(10E/1E), 1+(10k/1k) and 1+(100M/10M) Values. Which will give better response and why?

Gan is =(120/2,4)+1=51.
Vo=Gain*V1=51*120=6.12mV.
Vo=Gain*V1=51*120=6.12mV.

According to op-amp rules:
[(Vo-V1)/120k] = V1/2.4k
Solving for Vo gives 6.12mV
[(Vo-V1)/120k] = V1/2.4k
Solving for Vo gives 6.12mV

This is non inverting configuration so it's gain is (1+R2/R1)
and output voltage will be (1+R2/R1)*V1. Putting values we get answer.
