Explanation / Answer

Since the photo is not clear, considercng anion ti have a change of -x

F= 9*109*(product of charges)/(distance between charges)^2

F= 9* 109×*(2*1. 6*10-19*x*1. 6*10-19)÷(3.84×10-9)2

3.125x*10-11N (attraction)

Put x=2

We get

F=6.25 * 10-11 N

7.

C2H5NO

% of mass of C = mass of C÷ mass of molecule

C = 12g

H = 1g

O = 16g

N = 14g

Total mass =2*12+5*1+14*1+16*1

=59g

% mass of C =24/59*100

=40.6 %
