Question

Please Solve This Some Questions of Chemistry it's Very Important and very urgent for me.

Answer 1

Density = mass/ volume,

so,

m of sphere= 64 kg *1000 = 64000gm

(since volume is in ml which is equal to cm^3)

so,

volume = mass of cylinder with ball - mass of cyllinder with ball

=70ml-62ml

=8ml

d=m/v

d=6400gm/8ml

=800gm/ml or 800gm/cm^3
