Mole concept and law of equivalence

• for 100 rupees we buy 6 apple...but we cant take that for a account by asking 600rice partcile for 100 ruppeess....so when the size decrease the std measure like 1 kg is decided...

  
• 1kg=1000g this is a relation but how we can find that for 1 gram into 1amu

  
• to convert from amu to gram

  
  

  32 amu (atoms) of 6.022*10^23 times give one gram

  
• derivation

  
• so 12g of C12 = 6.022*10^23 important

  
• 1 mole is like a tharrasu (like one litre)

  
• h2o 18 gram/moles, co2=44 gram per moles .....

  
• to find the number of moles

  1.we use when weight of substance is given

  2.if the number of particle is given

  3.if it is the gas
• to find the number of moles

  1.we use when weight of substance is given

  2.if the number of particle is given

  3.if it is the gas

  
• question calculate 1 and 2 in 22g of co2

  
• if we are talking about moles, the number of moles is number of gmm,,

  if we are talking about atom,the number of moles is number of gramatom
• this is total numver of atom present in 22g of co2

  
• no of electron of CO2

  
• referece

  
• question1

  
• part-2

  
• q2

  
• part 2

  
• q3)if the wight of hydrogen inna sample is 30g, find the weight of the sample
• there is a difference between equivalent and equal....this is the example for equivalent

  
• formula becuase it acts only as the difference in charged particle. of outermost particle

  
• formula

  
• for acid ....basicity is H + ions.....

  
• basicity is based on the number of OH ion present in the compound

  
• so for example in this basicity is one because the OH is 1

  
• acidity is the amount of oh in the compound.

  
• in nh3 there is one acidity

  
• salt

  
• salt

  
• redox

  
• redox

  
• Q) 1

  
• part 2

  
• Euivalent weight is 4 types - acid, base, salt, redox reaction
• no of moles= given weight/ molar mass but here is different

  
• here no of gram eqivalent A= no of gram eqivalent B= no of gram eqivalentof c= no of gram eqivalentof D and it is used to find the elements accorfing to lay of conservation.............and in law of chemical equivalence we dont have to balance chemical equation

  
• lets prove that no of gram equivalent of reactants are same .....so divide no of mole (al) and its stoimetreyoc co efficient (4).............it is proved but i dont know how its equal

  
• question 1

  
• E is the equivalent rate of cooper(i dont know because then they done for oxygent )

  
• ans is CuO ( but i dont know how)
