Answer:
[tex]\large\boxed{\large\boxed{0.0400mol/liter}}[/tex]
Explanation:
Knowing that you have 64.92 grams of Hg(NO₃)₂ to make 5.00 liters of solution, you can calcualte the molarity of the solution.
Molarity is a measure of concentration, defined as the number of moles of solute per liter of soluiton. Mathematically:
[tex]Molarity=\frac{\text{number of moles of solute}}{\text{liters of solution}}[/tex]
Then, first you must calculate the number of moles of solute. The formula is:
[tex]\text{number of moles}=\frac{\text{mass in grams}}{\text{molar mass}}[/tex]
You can either calculate the molar mass of the compound using the chemical formula or search it in the internet.
The molar mass of Hg(NO₃)₂ is found to be 324.7 g/mol.
Now you have everything to calculate the molarity of the solution:
