HERE'S THE ANSWER..

_______________________________

♠️ We know momentum is product of mass
and velocity , and it is denoted by " P "

⏺️mass of electron ( m ) = 9 × 10^(-31) Kg

⏺️ velocity ( v ) = 6 × 10^(7) m / s

=> Momentum ( P ) = Mass ( m ) × Velocity ( v )

=> P = 9 × 10^(-31) × 6 × 10^(7)

=> P = 54 × 10^ ( -31 + 7)

=> $\boxed{P \:= \:54\:×\:10^{-24}\: kg\:m/s}$

Answer 2

p=m*v
p= 9 * 10 -31 kg * 6 * 10 7 m/s.
p=54* 10 -24 kg m/s
