n = number of moles (which is related to the mass of the gas, i.e. 1 mol = 6.023x1023 molecules of the gas, and n = mass (in grams)/molar mass(MM)), R = the ideal gas constant, and T = the absolute temperature.What...
The most common unit of concentration used by chemists is molarity (M). It is defined as the number of moles of solute present in exactly 1 liter of solution. When chemists ask, "What is the concentration of sucrose in the water," what do they mean? Submicroscopic particles are so very...
There are many forms of energy: electrical energy, potential versus kinetic energy, chemical (bond) energy or heat. Atoms or molecules can have electrical energy in the sense that the electrons can be gained or donated. Electrical energy is extremely important because the behavior of electrons det...
1 kg-mole =1000 moles >>> for CH4 MW =16kg/kg-mol or 16 g/mol. The quantity expressed inKJ/Kg-mol Kshould be divided by the molecular weight to get the right conversion inKj/Kg K., not as written above. https://www.engineeringtoolbox.com/specific-heat-c... If...
