Mole can be defined as the amount of substance that contains the same number of entities (atoms, molecules, ions etc) as the number of atoms present in 12g of the carbon −12 isotope. If we ask you to count the total number of stars in the sky, can you do that? The volume of water molecule is (take, density of water is 103 kg m−3 and avogadros number =6×1023 mole−1). Write (i) structural formula of the complex. When a co-ordination compound crcl3 ⋅6h 2o is mixed with agn o3, 2 moles of agcl are precipitated per mole of the compound. 1 mole gas at ntp occupies 22. 4 litre volume at stp. A solution of sucrose in water is labelled as 20 % w/w. Similarly, scientists can not count the exact number of atoms and molecules as they are too minute and … Atomic mass is the concept related to a single atom, whereas molecular mass relates to a group of atoms. What would be the mole fraction of each component in the solution? Mole fraction of a in vapours phase above the ideal liquid solution of a and b (xa = 0. 4) will be: (p o a = 100mm p o b = 200mm) : If you are planning to proceed with this concept, then it is necessary to gain precise … 1 mole oxygen and n2 have same volume at same temperature and pressure. Define mole fraction. Calculate energy of one mole of photons of radiation whose frequency is 5×1014.
