Answer:
The Earth's rotation on its axis
Answer:
200 g/L
Explanation:
The concentration of a solution (also called molarity) can be calculated with the formula:

where
m is the mass of the solute
V is the volume of the solution
For the solution in this problem we have:
m = 50g is the mass of the solute
V = 250 mL = 0.250 L is the volume of the solution
Therefore, the concentration of the solution is:

Explanation:
Perhaps the most important use of tin, historically, has been to make bronze — an alloy of copper and tin or other metals — that changed civilization by ushering in the Bronze Age.
