The answer is C. Aluminium since it is highly reactive
Answer:
0.906 gm/l
Explanation:
We know that molarity of the a solution is given by,
, where 'M' is the molarity, 'w' is the weight of the sample, 'm' is the molar mass, and 'v' is the volume of the solution.
Molarity of a solution tells us the concentration of the solute in the solvent.
Molar mass of KCl is = 74.55
Putting the values we get,
So the molarity of KCl solution is 0.906 gm/l.
