Mass of proton (p)=1.6726×10−27‌kg
Mass of neutron (n)=1.6749×10−27‌kg
Mass of electron (e)=9.1×10−31‌kg
Mass of proton is 1836.16 times heavier than electron.
Mass of neutron is 1838.68 times heavier than electron.
Ratio of mass of electron, proton and neutron will be
Mass of e : Mass of p : Mass of n
1:1836.16:1838.68
