The formula for finding the mole is:
mm = m / n
Molar mass = mass / number of mole
This can be changed to:
n = m / mm
For example:
You have a kilogram of carbon, how many moles are this?
Using the Periodic Table you will find that the molar mass is 12(.01078) g/mol
The mass is 1000 gram.
so: 1000 g / 12 g/mol = 83.33 mole

How do you Convert 40.79 kilojoules per mole to joules per grams?
To convert from kilojoules per mole to joules per gram, you need the molar mass of the substance. Once you have the molar mass, you can convert as follows: 1 kJ/mol = 1000 J/mol 40.79 kJ/mol = 40.79 * 1000 J/mol = 40790 J/mol Then, divide by the molar mass in grams/mol to get joules per gram.
How do I convert the enthalpy of vaporization of water in joules per gram from kiloJoules per mole?
Lets say, for example the enthalpy is equal to 1200 joules/gram. You take 1200 joules/gram * (# of grams)/one mole [now you can cancel grams and it is now joules/mole.] Then convert the answer to kilojoules by dividing by 1000.
How many kw in a kj?
1 kWh is a kilowatt-hour, in other words 1000 watts for one hour. That is 1000 Joules per second, for 3600 seconds. So 1 kWh is 3,600,000 Joules, or 3600 kJ.
What is 3923.7552 J into Kj?
To convert joules to kilojoules, divide by 1000. Therefore, 3923.7552 J is equal to 3.9238 kJ.
Specific heat capacity of zinc in J kgC?
Zinc sulfate is one of the three hydrates, and was historically known as white vitriol. It has the specific heat of 120 Joules per mole per degree Kelvin.
Energy in one mole of glucose in joules?
The energy content of one mole of glucose is approximately 2,810 kilojoules (kJ) or 2,810,000 joules (J).
What are the units for standard Gibbs free energy?
The units for standard Gibbs free energy are joules per mole (J/mol) or kilojoules per mole (kJ/mol).
How do you Convert 40.79 kilojoules per mole to joules per grams?
To convert from kilojoules per mole to joules per gram, you need the molar mass of the substance. Once you have the molar mass, you can convert as follows: 1 kJ/mol = 1000 J/mol 40.79 kJ/mol = 40.79 * 1000 J/mol = 40790 J/mol Then, divide by the molar mass in grams/mol to get joules per gram.
What is the energy (in joules) of an ultraviolet photon with wavelength 180nm?
1.11 atto Joules.
How do I convert the enthalpy of vaporization of water in joules per gram from kiloJoules per mole?
Lets say, for example the enthalpy is equal to 1200 joules/gram. You take 1200 joules/gram * (# of grams)/one mole [now you can cancel grams and it is now joules/mole.] Then convert the answer to kilojoules by dividing by 1000.
How many joules are in 4kcal?
The conversion is 4.2 Joules per calorie, so 4 kcal is 16.8 kJ.
Specific heat of NaOH?
Depends on the concentration of the solution. Most widely used concentration, i.e. 48% has Cp ~ 3.331 kJ/Kg.K
What is the standard enthalpy change for a reaction in kilojoules per mole (kJ/mol)?
The standard enthalpy change for a reaction is the amount of heat energy absorbed or released in kilojoules per mole (kJ/mol).
What unit is typically used when measuring ionization?
Kilojoules per mole. kj/mol
How do you convert kJ mol to J gram?
40.79 H2O kj/moles x 1 moles/18 grams= 2.266/1000=0.002266 joules/grams
What does One thousand joules equal?
one thousand joules equals a KJ
How many kw in a kj?
1 kWh is a kilowatt-hour, in other words 1000 watts for one hour. That is 1000 Joules per second, for 3600 seconds. So 1 kWh is 3,600,000 Joules, or 3600 kJ.
