Question

If the mass of neutron is doubled & mass of electron is halved then find out the new atomic mass
Illustrations
of 12C and the percent by which it is increased. detailed answer plz​

Answer 1

Answer:

6

C

12

→e=6

Number of protons = 6=6amu

Number of neutrons = 6=6amu

Total mass = (6+6)=12amu

Mass of the electron is negligible.

If the mass of the neutron is doubled, then the total mass = (6×2)+6= 18amu

Therefore, the % of the increase = =

12

18−12

×100=50%
