Question

calculate the percentage composition of each element in potassium chlorate KClO3​

Answer 1

Answer:

Hey mate here is your answer.

Explanation:

(Take the masses as K=39,CL=35.5,O=16,3(O)=3(16)=48),

Entire mass of KCLO3 is,

39+35.5+3(16),

39+35.5+48,

=122.5g.

So,percentage pf Pottasium(K)

39/122.5×100%,

=31.83%.

Now percentage of chlorine(Cl)

35.5/122.5×100,

28.97%.

So,finally percentage of oxygen(O)

3(16)/122.5×100,

48/122.5×100,

39.18%.

So,all masses are:

K=31.83%,

CL=28.97%,

O=39.18%,
