Question

Calculate the number of atoms in 52 moles of helium

Answer 1

Answer:

1 mole of he contain 6.023×10^2352 moles of he contain 52×6.023×10^23

Answer 2

ANSWER:1)SOME EXTRA INFORMATION

• 1 mole of he contains 6.023×10^23.Thus,52 mole of he contain 52×6.023×10^23.
• Atomic mass oh he is 4u equal to 2 Proton + 2 Neutron=1 atom.Thus,No. of atom in 52 u=52/4=13 atom.
• 4g of he has 1 mole.Thus,1g of he kas 1/4 mole.Therefore,52g of he has 1/4×52=13 mole.
• Since,1 mole is 6.023×10^23.
• Therefore,52 mole=52×6.023×10^23 atoms
