Answer:
The right answer to this question is: True
Step-by-step explanation:
Water is a substance known for the whole world as the universal solvent, and that can mean lots of different things, but the main one is that water, as a solvent, will dissolve most of the other substances when they're poured with it. Besides that, the solvent will almost always be in a higher quantity that the solute, in this case, there are only 0,5g of NaCl and 100g of H2O, so by that, we can be sure that the water is the solvent, and the NaCl is the solute.
