A mixture means two or more substances forming into one new substance, look at your answers that you have. Does it show two or more different substances that chemically change into one new substance?
No it is an amino acid present in the synthesis of certain proteins. Elements are pure substances so an acid (which is a compound of different elements) would not be considered an element.

Hello!
I'm going to have to infer that you meant "grams" and not "gallons" :-)
Anyways, to find the density, you need to the divide mass over volume (d = m/V).
Since we are given the volume being 15.0 mL, and the weight being 40.5 grams, we can find the density of the aluminum block.
40.5 grams / 15.0 mL = 2.7 g/mL
Therefore, the density of the aluminum block is 2.7 grams per milliliter.
