Moreover, the main difference between both is that molar mass gives the mass of a mole of a particular substance. Whereas molecular weight is the mass of a molecule of a particular …
A solution contains 1 mole of water and 4 moles of ethanol. The mole fraction of water and ethanol will be:
(A) 1 faraday = 96,500 coulomb. It is a charge of 1 mole electrons. (R) 1 faraday charge liberates one gram equivalent of substance at an electrode. Assertion (A) is true but reason (R) is false …
Atomic mass is the concept related to a single atom, whereas molecular mass relates to a group of atoms. If you are planning to proceed with this concept, then it is necessary to gain precise …
Two liquids A and B form ideal solutions. At 300K, the vapour pressure of solution containing 1 mole of A and 3 mole of B is 550mmH g. At the same temperature, if one more mole of B is added to …
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? No. Similarly, scientists can not count the exact number of atoms and molecules as they are too minute and too many. …
A solution of glucose in water is labelled as 10 % w/v, what would be the molality and mole fraction of each component in the solution? If the density of the solution is 1.2 g mL−1, then what shall be …
One mole of potassium chlorate (KClO3) is thermally decomposed and excess of aluminium is burnt in the gaseous product. How many moles of aluminium oxide (Al2O3) are formed?
Question 39 Concentration terms such as mass percentage, ppm, mole fraction and molality are independent of temperature, however molarity is a function of temperature. Explain.
