64.92 grams of Hg(NO3)2 to make 5.00 liters of solution.

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:

Then, first you must calculate the number of moles of solute. The formula is:

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:

i believe it is a.) released into

explanation:

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
