Answer :
Scalar: Density, mass, speed, volume, angular frequency, number of moles.
Vector: Velocity, acceleration, angular velocity, displacement.
A scalar quantity is determined solely by its magnitude and is unaffected by its direction. Scalar quantities include density, mass, speed, volume, angular frequency, and the number of moles.
The magnitude and direction of a vector quantity are both important. This includes velocity, acceleration, angular velocity, and displacement.
