How many Moles of solute (mol)? The molar mass of CaCl2 is 110.98 g/mol. 7.) What is the Mass of solvent in grams? Add together the masses of the liquid water and ice added to the calorimeter. Convert the volume of liquid water to mass using 1.000 g/mL as the density of water (see procedure for volume used). 8.) What is the Mass of solvent in kilograms?
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
6.) How many Moles of solute (mol)?
The molar mass of CaCl2 is 110.98 g/mol.
7.) What is the Mass of solvent in grams?
Add together the masses of the liquid water and ice added to the calorimeter. Convert the volume of liquid water to mass using 1.000 g/mL as the density of water (see procedure for volume used).
8.) What is the Mass of solvent in kilograms?
Use the metric definition 1 kg = 1000 g
9.) What is the Molality of the solution (m)?
molality (m)=moles of solute kilograms of solvent molarity (m)=moles of solute kilograms of solvent
