Question

determine the number of atoms in 0.356 of gold

Answer 1

if thats moles multiply 0.356 by avogadro's number (6.023 x 10^23)

Answer 2

i dont get what to write as an answer

Answer 3

a mole is constituted of 6.023 x 10^23 atoms (or molecules if you had say H2O)

a mole is analogous to saying a dozen.. if you had a dozen of gold atoms you would have 12, if you had a mole of gold atoms you would have 6.023 x 10^23 atoms.

so you have 0.356 moles of gold (Au), correct?

1 mole = 6.023 x 10^23 atoms

0.356 moles is the proportion of atoms you have.. if you had 0.25 of a dollar, you have 25 cents, right?

so 0.25 x 1 dollar = 0.25 of a dollar.

similarly, 0.356 moles (6.023 x 10^23 atoms) = 2.14 x 10^23 atoms of gold (Au)

Answer 4

Thank you very much :)

Answer 5

no prob !

Answer 6

when you say that its 0.356 of gold do you mean to say 0.356 moles or 0.356 grams??
