Answer :
Molarity H°rxn = Qrxn/(number of moles of AgNO3) = (1170.4 J)/(0.03 mol) ≈ 39013.33 J/mol = 39.013 kilojoules.
How do mol and molarity work?
The term "Molarity" is derived from the unit of measurement called a mole, which is used to describe chemical substances. Calculating how amount of substance present in a certain chemical solution is done using a concept known as molarity, commonly known as the molar concentration of a solution.
Using the equation Q = m.c.T, Q =??? J, where Q is the quantity of heat produced by the solution, we can figure out the amount of warmth (Q) released from the solution.
The specific heat capacity (c = 4.18 J/g°C) of the solution determines its mass, or m, which is equal towards its density times volume, and (1.0 g/mL) divided only by volume, or 200 g.
(23.20 vs. 1.4) degrees Celsius is the difference in temperature (T) between the initial and final temperatures.
∴ Q = m.c. T = 200 g (at 4.18 J/g°C and 1.4 °C, respectively) = 1170.4 J. H°rxn = Qrxn/(number of moles of AgNO3)
The number of moles of immediately following in a solution that has a volume of 1.0 liters is known as molarity (M).
M is equal to (number of moles of AgNO3)/(volume of a solution (L)).
