Is moles and molarity the same thing?
Mole is a measurement of the number of substances, whereas molarity is a measurement of the concentration. Molarity gives an idea of the amount of substances present in a mixture. Molarity is given as moles of a substance in one volume of a solvent. A mole is a unit whereas molarity is not.
How do you find moles with molarity and liters?
Compute the volume of a solution in liters, given the number of moles and molarity, by dividing the number of moles by the molarity in units of moles per liter. For example, a solution containing 6.0 moles and a having a molarity of 3.0 moles per liter has a volume of 2.0 moles per liter.
How do you find the mass percent?

How do you find the molarity of an element in a compound?
To calculate the molarity of a solution, you divide the moles of solute by the volume of the solution expressed in liters. Note that the volume is in liters of solution and not liters of solvent. When a molarity is reported, the unit is the symbol M and is read as “molar”.
How can molar mass be calculated?
To calculate the molar mass of a compound, calculate the molar mass of each element in the compound, then multiply the element’s atomic mass by the number of atoms of that element in the compound. Add the molar masses of each element in the compound to calculate the molar mass of the compound!
How do you find grams in a solution?

How do you convert moles to kJ mol?
The prefix “kilo” means 1,000, so one kJ = 1,000 J. As the energies associated with a single molecule or atom are quite small, we often find it easier to discuss the energy found in one mole of the substance, hence “per mole”. To get the energy for one molecule, divide kJ/mol by Avogadro’s number, 6.022 x 1023.
Is kJ the same as kJ mol?
kJ is the units “Joules” multiplied by a number (kilo = x1000) that has no units of it’s own. kJ/mol is just the J multiplied by a number that has no units on it’s own: 1000/mol.
