How do you calculate for linear mass density?

To calculate for linear mass density, find the mass of the object, measure the length of the object, and divide the mass by the length. Linear mass is typically investigated in terms of a string.

1. Find the mass

   Determine the mass of the string by directly weighing it with a scale.

2. Find the length

   Determine the length of the string by using a measuring device, such as a tape measure.

3. Calculate the linear density

   Divide the mass by the length. The quotient is the linear density of the length of the string weighed and measured. The expression used to describe this equation is that linear density is the mass of the string per unit length.
