Do you know about any dangers related to these substances? As chenbeier already asked: do you know, how to handle these substances?

Would you prefer to weight the sample, or to measure the volume? Which sounds easier and more accurate? Which will be easier to do (depending on the laboratory equipment you have)?

That equipment you can and should use. But which substance you will choose and why.
