There is no direction in number of moles, so it is scalar.
Since you can represent that with a single number, it isn't a vector - just a scalar.

scalar
A scalar is a magnitude that doesn't specify a direction. A vector is a magnitude where the direction is important and is specified.
The product of a vector and a scalar is a new vector whose magnitude is the product of the magnitude of the original vector and the scalar, and whose direction remains the same as the original vector if the scalar is positive or in the opposite direction if the scalar is negative.
Amount of substance is a scalar quantity. It is a measure of the number of entities (such as atoms, molecules, or ions) in a sample, and does not have a direction associated with it like vector quantities.
A scalar is just a number. A vector is a row or column of numbers. For example: 6 is a scalar while (1, 0, 23.5) is a vector.
A scalar times a vector is a vector.
scalar lol
vector
A positive scalar multiplied by a vector, will only change the vector's magnitude, not the direction. A negative scalar multiplied by the vector will reverse the direction by 180°.
The number of passengers on a plane is a scalar quantity. Scalars have only magnitude and do not have direction.
Yes, the magnitude of a vector is a scalar.
Since you can represent that with a single number, it isn't a vector - just a scalar.
Yes, you can add a scalar to a vector by adding the scalar value to each component of the vector.
1000000 is a number and therefore it is a scalar. A scalar cannot be represented as a vector.
A scalar quantity added to a vector quantity is a complex quantity. An example is a complex number z = a + ib, a is the scalar and ib is the vector quantity.If the vector quantity is 3 dimensional, ib + jc + kd, then the scalar and vector forms a quaternion quantity.
