Question

if in C mass of proton is halfed , mass of neutron is tripled and mass of electron is doubled than calculate •/• change in mass.​

Answer 1

your answer: -

a element have,

electron=6

proton= 6

neutron=6

initial mass - mass of Neutron+ mass of proton

==> 6+6

==> 12 amu.

final mass = mass of Neutron + mass of proton

==> 3×6+6/2

==> 18+3

==> 21amu.

we know that,

•/• change in mass =

(final mass -initial mass) ×100

(initial mass)

==> (21 -12) × 100

12

==> 9 ×100

12

==> 75•/•

75•/• Ans.
