An amoeba has 1.55 × 10 16 protons and a net charge of 0.790 pc. (a) How many fewer electrons are there than protons? X electrons Enter a number (b) If you paired them up, what fraction of the protons would have no electrons? protons without electrons protons Additional Materials Reading

Explanation / Answer

From the given question.

a)Number of protons= 1.55*10^16 =np

Number of electrons= ne

net charge=0.790 pC = (np-ne)*1.6*10^-19

np-ne=(0.79*10^-12)/(1.6*10^-19)

solving we get, np-ne=4937500

There are 4937500 fewer electrons.

b) protons without electrons/ protons= (4937500 )/(1.55*10^16)=1:(3.14*10^9)
