Alfred Wegner was the first person to propose the idea that all seven continents were all one supercontinent called "Pangea". Everyone considered his theory to be a joke until he found evidence to back up his theory. His evidence was the matching mountain ranges, fossils, certain species, and more over different continents. Also that all the seven continents fit together like puzzle pieces. I hope this helps! :)
        
             
        
        
        
Hi!
To make 500 mL of a 1,500 M solution of NaCl you'll require 
43,83 g
To calculate that, you will need to use a conversion factor to go from the volume of the 1,500 M solution to the required grams. For this conversion factor, you'll use the definition for Molar concentration (M=mol/L) and the molar mass of NaCl. The conversion factor is shown below:

Have a nice day!
