How many atoms of zinc are in 0.60 mol of zinc? 2. how many moles is 3.52 × 1024 molecules of water? 3. how many atoms are in 2.00 moles of li? 4. how many moles are in 6.02 x 1023 atoms of carbon? 5. how many moles are in 4.9 x 1023 molecules of zncl2?
question 1 by use of Avogadro law that is,1 mole = 6.02 x10^23 atoms what about 0.60 moles by use of cross multipication
=(0.60 mole/ x 6.02 x10^23)/ 1mole = 3.612 x10^23 atoms of Zn
question 2 by use of Avogadro law constant that is 1 mole =6.02 x10^23 molecules what about 3.52 x10^24 molecules by cross multiplication =( 1 mole x3.52 x10^24 molecules/6.02 x10^23 molecules) = 5.847 moles of water
question 3
by use of Avogadro law constant 1 mole = 6.02 x10^23 atoms what about 2 moles =? atoms by use of cross multiplication =( 2moles x 6.02 x10^23 )/1mole= 1.204 x10^24 atoms of Li
question 4
by use of Avogadro law constant 1 mole = 6.02 x10^23 atoms what about 6.02 x10^23 atoms =? moles cross multiplication (1 mole x6.02 x10^23 atoms)/(6.02 x10^23 atoms)= 1 mole of carbon
question 5 by use Avogadro law constant 1 mole =6.02 x10^23 molecules what about 4.9 x10^23 moles =? moles by cross multipication =( 1mole x 4.9 x10^23 molecules) /6.02 x10^23 molecules = 0.81 moles ZNCl2
