Answer:
The sample size is 601.

Given information:
Confidence interval = 95%
E = 4% = 0.04
From the z table it is clear that the z-value 95% confidence is 1.96.
A researcher wants to determine the proportion of pro-peace students at Rutgers University.

Formula for sample size is

Substitute the given values in the above formula.



Sample size can not be a decimal value. So, round the answer to the next whole number.

Therefore, the sample size is 601.
When sodium chloride is molten:
NaCl ------> Na⁺ +Cl⁻
Anod (+) | Cathode (-)
2Cl⁻-2e⁻ ---> Cl2(gas) | Na⁺ + e⁻ -----> Na⁰(s)
