Find the molar heat of the combustion candle by multiplying the change in heat by the moles of candle that were burned. Given that the change in water is equivalent to the change in candle heat, the latter is therefore equal to 20,920 joules. Multiply this by .0056 moles to obtain an ...
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)=...
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. To calculate the molar heat of vaporization, write down your given informa...
In general, in order to find the molar heat capacity of a compound or element, you simply multiply the specific heat by the molar mass. For example, the specific heat of methane (CH4) is 2.20 J/g-K. To convert to molar heat capacity you can make use of the molar heat capacity formu...
How do you calculate the average volume of acid used in titration? When a 6.00 g sample of RbBr is dissolved in water in a calorimeter that has a total heat capacity of 2.09 J/K, the temperature decreases by 0.380 K. Calculate the molar heat of the solution of RbBr. ...

To find the median, you first put all the numbers in ascending order, from smallest to biggest, and then you pick the one in the middle. This simple yet effective way allows us to understand a lot of data with just one number. How to find Median To find the median, simply line up ...
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 ...
