Understanding Moles Gcse Chemistry Youtube An element in its solid phase has mass density 1750 kg m^3 and number density 4.39×10^28 atoms m^3. what is the element's atomic mass number? learn moles and avogadro's number with free step by step video explanations and practice problems by experienced tutors. 📚 the modern definition of a mole is related to avogadro's number, which is the number of atoms in exactly 12 grams of carbon 12. 🌐 moles are not only used in chemistry but can theoretically be applied to count any type of entities in a given mass that corresponds to their atomic or molecular mass. Key takeaways: mole in chemistry. the mole is an si unit used to measure the amount of any substance. the abbreviation for mole is mol. one mole is exactly 6.02214076×10 23 particles. the "particles" could be something small, like electrons or atoms, or something large, like elephants or stars. The mole is related to the mass of an element in the following way: one mole of carbon 12 atoms has 6.02214076 × 10 23 atoms and a mass of 12 grams. in comparison, one mole of oxygen consists, by definition, of the same number of atoms as carbon 12, but it has a mass of 15.999 grams. oxygen, therefore, has a greater mass than carbon.

Easy! work out the relative formula mass, and then add the unit "grams". example 1: the mass of 1 mole of water, h2o. the relative formula mass of water, h 2 o = (2 x 1) 16 =18. 1 mole of water, h 2 o, weighs 18 g. example 2: the mass of 1 mole of sodium carbonate crystals, na2co3.10h2o. Definition. 1 mole of a substance is defined to be the amount of the substance containing as many atoms, molecules, ions, electrons or other elementary entities as there are carbon atoms in 12 grams of ^ {12}\ce {c}. 12c. this number is known as the avogadro constant ((abbreviated n 0 n 0 or n a). n a).
