Final answer:
The A) concentration of the magnesium nitrate solution cannot be determined with the given information.
Step-by-step explanation:
The concentration of the magnesium nitrate solution can be calculated using the given information. First, we need to determine the number of moles of silver (Ag) reacting with the magnesium nitrate (Mg(NO3)2) solution. We can calculate the moles of silver by using its molar mass and the given mass:
Moles of Ag = Mass of Ag / Molar mass of Ag
Then, using the balanced chemical equation, we can determine the stoichiometric ratio of magnesium nitrate to silver. Based on this ratio, we can calculate the moles of magnesium nitrate:
Moles of Mg(NO3)2 = Moles of Ag * (Moles of Mg(NO3)2 / Moles of Ag)
Finally, we can calculate the concentration of the magnesium nitrate solution by dividing the moles of magnesium nitrate by the volume of the solution in litres:
Concentration = Moles of Mg(NO3)2 / Volume of solution (in L)
Since the mass of the magnesium nitrate solution is not given, we cannot determine the concentration with the given information. Therefore, the correct answer is A) Concentration cannot be determined with the given information.
