Boiling Point, Melting Point, Viscosity, Surface Tension. Decrease: Vapor Pressure.
I think it is trace evidence since it is really small and hard to find.
Answer:
78 moles of the solute
Explanation:
From the question;
- Molarity of the solution is 6.50 M
- Volume of the solution is 12.0 L
We want to determine the number of moles needed
We need to know that;
Molarity = Number of moles ÷ Volume
Therefore;
Number of moles = Molarity × Volume
Hence;
Number of moles = 6.50 M × 12.0 L
= 78 moles
Thus, the moles of the solute needed is 78 moles
Rutherford found protons
Thompson found electrons and
Bohr crewed the Bohr model the most commen model of the atom used today
This really a your opinion question but my favor is Bohr
