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 you convert joulesmole to joulesatom?
There are 6.02 x 1023 atoms per mole so divide the term in J/mol by 6.02 x 1023 to get J/atom.
What is -1211.5 joules per kelvin converted to kilijoules per moles?
To convert -1211.5 J/K to kJ/mol, we need to take into account the molar mass of the substance. If we assume the molar mass is 1 g/mol, then -1211.5 J/K is equal to -1.2115 kJ/mol.
How much energy in joules must be absorbed to convert to Na all the atoms present in 1mg of gaseous Na when the first ionization energy is 495.8 kj per mol?
The first step is to calculate how many moles of Na are present in 1 mg (0.001 g) of Na. Since the molar mass of Na is 22.98977 g/mol, there are 0.000043 moles of Na. Next, convert the ionization energy to joules by multiplying by 1000 (1 kJ = 1000 J) to get 495,800 J/mol. Finally, multiply the number of moles by the energy per mole to find the total energy required: 495,800 J/mol * 0.000043 mol = 21.3 J.
How do I convert the enthalpy of vaporization of water in joules per gram from kiloJoules per mole?
To convert the enthalpy of vaporization of water from kJ/mol to J/g, you need to divide the given value in kJ/mol by the molar mass of water (18 g/mol). This will give you the enthalpy of vaporization in J/g.
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
If 6 moles of a compound produce 84 J of energy what is the delta H reaction in jmol?
The enthalpy change (ΔH) per mole can be found by dividing the energy produced by the moles of the compound. In this case, ΔH = 84 J / 6 mol = 14 J/mol. Therefore, the enthalpy change per mole of the compound is 14 J/mol.
What quantity must the heat capacity of an object be divided to obtain the specific heat of that material?
Heat capacity is in the measurement of (kilo)Joules per mol degree Kelvin (J/mol K) Specific heat capacity is in joules/gram degree Kelvin (J/ gram K) Converting between the two is rather simple. To convert to specific heat capacity, divide the molar heat capacity by the molar mass of the molecule in question. eg. ( J/ mol K) / (grams/mol ) = J/ gram K, because mols will cancel.
If 6 moles of a compound produce 84 J of energy what is the H reaction in J mol?
-14 J/Mol
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).
The binding energy of electrons in a metal is 178kJ per mol what is the threshold frequency?
use the formula E=hv where v is the threshold frequency.however, the binding energy is in kJ per mol. convert it into J per atom.178kJ times 1000 = 178000 J and then divide by Avogadro's number (6.022*10E23)after that u just plug the number in equation wher h is planck's constant (6.626*10E-34 J*S) and solve for v (frequency)this will definitely work.
What is the heat of solution for barium chloride in joules?
The heat of solution for barium chloride is -61.7 kJ/mol. To convert this to joules, multiply by 1000 to get -61,700 J/mol.
