If you find an element that exists as only one isotope, then the atomic mass and the atomic weight will be the same. Atomic mass and atomic weight may equal each other whenever you are working with a single isotope of an element, too. In this case, you use the atomic mass in calculat...
When discussing molar mass and conversions in chemistry, Avogadro's Constant is crucial as it bridges the microscopic world of atoms and molecules with the macroscopic world of grams and moles, providing a measurable quantity with units. Meanwhile, Avogadro's Number, though numerically the same, of...
molality is a solution property and is defined as the number of solvent moles per kilogram. molality’s si unit is mol/kg. a solution with a 3 molar/kg molality is often defined as “3 molal” or “3 m.” however, it is now preferred following the unit si system, mol/kg or a ...
The Molecular Formula indicates the actual number of atoms of each element, whereas the Empirical Formula shows the simplest ratio. 15 Is the molar mass related to the Molecular Formula? Yes, the Molecular Formula is directly related to a compound's molar mass. 12 How is the Empirical Formula...

A 0.029 m^3 tank contains 0.072 kg of Nitrogen gas (N2) at a pressure of 3.67 atm. Find the temperature of the gas in Celsius. Take the atomic weight of nitrogen to be N2 = 28 g/mol. If 37.5 mol of an ideal gas occupies 28.5 L at 437 K, what is the pressure of the gas?
To this aim we have compared the insertion of apolipoproteins A-I and A-II in phospholipid monolayers formed on a Langmuir trough in conditions where lipid packing, surface pressure and charge were controlled. We also used atomic force microscopy to obtain high resolution topographic images of ...
The key difference between exact mass and molecular weight is that exact mass is the average mass of the atoms of an element measured in the atomic mass un
to fulfil this gap and measure the particles in a macroscopic level, molar mass concept is useful. The definition of molecular weight is directly related to the carbon-12 isotope. The mass of one mole of carbon 12 atoms is exactly 12 grams, which is its molar mass is exactly 12 grams pe...
