Question

Calculate the charge on 6.35g copper. If 2% of it's electron is removed

Answer 1

Answer:

ExplanationGiven mass=6.35g

At mass=63.5 Atno.=29(which is total no. Of e-)

No. Total no. Of electrons in 63.5g=6.35×29/63.5

Now in 6.02×10^23 atoms=2.9×6.02×10^23=1.74×10^24

According to the question:

2% of e- is removed i,e no. Of e- left=2×1.74×10^24/100

=1.705×10^24

Now the net charge on cu Q=ne

i,e=1.7×10^24×1.6×10^-19c

=2.72×10^5

I hope u find the answer pretty well.

Do ask some questions.

All the very best
