9. To find the mass of
atoms of gold, we need to use Avogadro's number, which is
atoms/mol. First, we need to find the molar mass of gold (Au), which is 197.0 g/mol.Next, we can calculate the number of moles of gold atoms:Number of moles =
Now, we can calculate the mass of gold atoms:Mass = Number of moles * Molar mass of goldMass =
* 197.0 g/molAfter performing the calculation, we find that the mass of
atoms of gold is approximately 2.04 x 10^6 grams.10. To find the number of carbon atoms in 100 grams of glucose (
), we need to use the molar mass of glucose, which is 180.16 g/mol.First, we can calculate the number of moles of glucose:Number of moles =
Next, we can calculate the number of carbon atoms in one mole of glucose:Number of carbon atoms in one mole of glucose = 6Finally, we can calculate the total number of carbon atoms in 100 grams of glucose:Total number of carbon atoms = Number of moles * Number of carbon atoms in one mole of glucoseTotal number of carbon atoms =
* 6After performing the calculation, we find that there are approximately 3.33 moles of carbon atoms in 100 grams of glucose.
