Answer:
B) any complex thing with properties normally associated with living things
C, because a homogeneous mixture is evenly mixed.
All those others would be heterogeneous (not evenly mixed).
If you mean hydrate as in <em>MgSO4 · 7H2O, </em>then simply find the molar mass of each element you see.
For the example above, that means you would add the molar mass (found on the periodic table) of Mg, then S, then 4(O), 14(H), and 7(O).
The results would be your molar mass for the hydrate.
I hope this is what you meant by your question!
Nitrogen is ...19.7
flourine is 80.3...
hope this helps!
