Question

number hydrogen atoms present in 10 moles of hydrogen atoms​

Answer 1

10×avagadro no.(I.e. 10×6.022×10^23)

no. of atom in one mole is equal to 6.022×10^23 then

no.of atom in 10 mole equal to 10×6.022×10^23

Answer 2

H2 is Hydrogen Atom ....

so ,

Mass of H2 = 1*2 = 2g = 1 mole

then ,

10 moles = 2*10 = 20g = 10 atoms
