<span>Activity series of metals. it is a series of metals based on their reactivity from highest to lowest. Potassium occupies the top most level of reactivity. The reactivity means the ability to displace hydrogen gas from water and acid solutions.</span>
Answer:
Evaporation from the hydrosphere provides the medium for cloud and rain formation in the atmosphere. The atmosphere brings back rainwater to the hydrosphere. The atmosphere provides the geosphere with heat and energy needed for rock breakdown and erosion. The geosphere, in turn, reflects the sun's energy back into the atmosphere.

Explanation:
If you are trying to find the molarity of this solution you first need to find the number of moles of sodium chloride that are present in the 0.5g sample. To do this you need to divide the mass of sodium chloride (0.5g) by its molar mass (58.45g/mol) to get 0.00855mol of sodium chloride. Then you divide the number of moles (0.00855mol) by the volume of solution (0.05L) to get 0.171M (The units for molarity is mol/L). Therefore the solution has a concentration of 0.171M.
I hope this helps. Let me know in the comments if anything was unclear or if you were asking a different question.<span />
