Answer:
375 g
Explanation:
Let the total mass of the solution = x g
Given that the mass of NaOH in the solution = 15.0 g
Thus, mass of the solvent = x - 15.0 g
Given that the mass % of the solution = 4 %
So,
So,
<u>Mass of the solution = 375 g</u>
Lol your in my science class. i believe its plutonium-239, but if someone else says I'm wrong listen to them. I'm not too sure.
Analyzing a biomolecule X, a scientist verifies that it is made up of Carbon, Hydrogen, Oxygen and Nitrogen, in addition to releasing water when it joins with other similar molecules to form polymers. Considering these antecedents, it can be inferred that biomolecule X corresponds to: A Steroids B fatty acid C nucleotide D amino acid E monosaccharide (for people who dont speak spanish)
ok you answer is probably A
if wrong C maybe
~hope~
