Answer:
Explanation:
Convert molecules to moles:
1 mole of NaNO₃= 6.02 x 10^23 molecules of NaNO₃
7.3 x10^24/(6.02 x 10^23)=12mol NaNO₃
Find molar mass:
NaNO₃=1 mole of Na and 1mole of N and 3mole of O
Find grams:
14.01g x 12= 168.12 g of N
It would be false adding a solute to a solvent
D. all of the above, although I do find it hard to believe something like flour would have a melting point, I looked up my answer to double check.
