The molar heat capacity is the amount of heat that must be added to raise the temperature of 1 mol of a substance by 1 degree. The molar heat capacity formula is when you multiply the specific heat by molar mass. The greater the heat capacity, the more h

The molar heat of vaporization is the energy needed to vaporize one mole of a liquid. The units are usually kilojoules per mole, or kJ/mol. Two possible equations can help you determine the molar heat of vaporization.
https://www.dropbox.com/s/vr99iv1u9k56q3p/dd.png?dl=0 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 r...
Calculate the change in the internal energy of the gas. The molar heat capacity of the gas at constant pressure, Cp=6.82calK−1mol−1 and R=1.987calK−1mol−1. View Solution The volume to be excluded due to only two molecules of a gas in collision with a fixed point of ...

Specific Heat Capacity (c here) of a substance is the heat required (q) to raise the temperature of 1 unit mass of that substance by 1 unit c=qmΔT Where ΔT is the change in temperature The more heat you require to change the temperature of one unit mass of a substance by one ...
Using Molar Mass Now, you can tackle the question at the beginning of the article. Say you need to make 1 L of a 1M NaCl solution. How do you know how much salt to weight out? First, you will need to find the number of moles you need for this solution. To do this, you will ...
We will use the equation that includes the molar gas constant to calculate the internal energy of this gas: U=1.5nRT=1.5(2.5mol)(8.31Jmol⋅K)(290K)≈9000J The internal energy of the gas is 9000 Joules. Example 2 A sample containing8.5×1024molecules of a gas is at a temperature...
b) Calculate the enthalpy of the reaction (in kJ/mol). Show all steps of calculation. Homework Equations it was given on the previous page that m = delta Volume * (-11.05) The Attempt at a Solution I got part a, but I am having a lot of trouble with part b. I am not even sur...
