Question

18.066×10^23 no.of helium atoms... How many moles it contains

Answer 1

hope this helps you dude

Answer 2

Answer:

given = 18.066×10²³ no of helium atoms

to find =   moles =?

solution=  

•                                       1 mole =  6. 022 ₓ10 ²³

               so,   no of heliums atoms =  6.022 × 10 ²³/  18.066×10²³

                                                          =   3 moles

18.066×10²³ atoms contain 3 moles .
