How Can the Linear Density be Determined Experimentally in Melde's Lab?

[NIZBIT]

This lab is basically the relationship between frequency and tension for a standing wave. One question I have though. In the lab I'm doing it states, "Calculate the linear density and determine it experimentally..." Calculating it is no problem, but how can I determine it experimentally? We never weighed or measured the total length of the string so I don't see how this can be done

You have to weigh the string and measure its length.

Thats what I thought and we never made those measurements. Time to yell at the teacher.
