Answer to Question #210607 in Biochemistry for ARCHIE MEDINA

Question

how many moles containe each of the following?

a.4.65x10²⁴ atoms C u

b.2.75x10²⁵ molecules CH₄

_{find the molar mass}

_1.CC1

_2.C₆H₁₂O₆

Answer 1

a). 1 Mole=6.023x10^23 atoms

____?___=4.65x10^24 atoms of Copper

=4.65x10^24 atoms x 1 mole%6.023x10^23 atoms =7.72x10^46 moles

b). 1 Mole =6.023x10^23 molecules

____?___=2.75x10^25 molecules of CH4 Molecules

=2.75x10^25 x 1 Mole % 6.023x10^23 = 4.57x10^47 moles
