## Main Question or Discussion Point

Can anyone tell me what the density of salt is on average? I know there are many types of salt, but there must be an average value to this right?

Because I’ve got the volume of this salt particle and I need its density in order to work out the mass.

I also want to plot a graph of Intensity against scattered angle, for the diffraction of laser light by particles. But I have voltage values instead of intensity values, Shall I still use the voltage values for my graph or do I convert it to intensity values?

Thanks a lot
