What does the heat capacity of an object depend on? Calculate the heat given off when 177 g of copper cools from 155.0 degrees C to 22.0 degrees C. The specific heat capacity of copper is 0.385 J/g degrees C. Calculate the heat capacity, in joules and in calories per degree, of 37.1...
My attempted answer is below: I'm struggling to find the mass. Is the mass 50.0mL + 25.0mL = 75.0mL solution It says to assume 1mL solution = 1g solution Is this referring to the solution or just the water? If it is referring to the solution, would the mass be 75.0g? q(soln)=...
FAQ: How to Calculate the Number of Moles in a Gas Using the Ideal Gas Law? What is the definition of a mole in scientific terms? In chemistry, a mole is a unit of measurement used to express the amount of a substance. It is defined as the amount of a substance t...
Calculate S for the conversion of 1 mole of a liquid (H_2O) to vapour at 100^oC, given that the heat of vaporization of water is -2260.87J/g. Knowing that \DeltaHvap for water is 40.7 kj/mol, calculate Pvap of water at 37^{\circ} Celsius. Calcu...
Example 2: Calculate the enthalpy change per mole of carbon monoxide for the reaction of carbon monoxide with oxygen to give carbon dioxide. Carbon burned with limited oxygen will result in carbon monoxide (CO), however, when there is sufficient oxygen, the product will be carbon dioxide (CO2...

How to Calculate Particle Concentration. The particle concentration within a solution describes the number of particles dissolved in the solvent. A solution may contain billions upon billions of particles, so chemists, for convenience, specify the amount
If you have a simple reaction between two molecules and know the bond enthalpies of the individual bonds, you can use the following relationship to calculate the total enthalpy change for the reaction. If it is negative, heat is released, and the reaction is exothermic; if positive, the react...
Thank you guys, I think I have a solution to calculate Cp for all my substances as shown above and I have also learned how to calculate R which means I know have Cp, Cv and R. One more question. To calculate Cp value I use TABLE 2-198 Heat Capacities of Inorganic and Organic Compo...
Calculate the coefficient of molar absorption according to the equation A = ecl, where A is absorbance, c is concentration in moles per liter and l is path length in centimeters. Solved for e, this equation becomes e = A / (cl). Continuing the example from Step 2, tetraphenylcyclopentadie...
