Basic Concepts of Chemistry
This video explains the concept of mole in terms of mass, volume, number and density, calculation of mass percent, volume percent and mole fraction.
- what is the basic difference between a mole and molar?
- if mass of 2 atoms of an element is 4×10^-23grams, then atomic mass of element will be: ( take: avagadro number =6×10^23
- The maximum number of molecules is present in. (a) 15 L of H2 gas at STP (b) 5 L of N2 gas at STP. (c) 1.5 g of H2 gas (d) 5 g of O2 gas
- molarity
- mole
- Number of carbon atom present in 22 gram of CO2 is
- calculate the number of hydrogen atoms and oxygen atom in 1 mole of water!
