Question

Define :) 1)
molecular mass 2) velocity​

Answer 1

Answer:

molecular mass -- The molecular mass is the mass of a given molecule: it is measured in daltons. Different molecules of the same compound may have different molecular masses because they contain different isotopes of an element.

velocity--The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion

Answer 2

Answer:

1) The molecular mass (m) is the mass of a given molecule: it is measured in daltons (Da or u). Different molecules of the same compound may have different molecular masses because they contain different isotopes of an element.

2) The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north)

• In SI base units: m/s

• Other units: mph, ft/s

• Common symbols: v, v, v→

• Dimension: L T^−1
