Final answer:
To find the number of moles of gold in 5.00 ounces, we can use a conversion factor involving the molar mass of gold. By converting the mass in ounces to grams and then to moles, we can determine that there are approximately 0.723 moles of gold in 5.00 ounces.
Explanation:
To determine the number of moles of gold in 5.00 ounces, we need to use a conversion factor. The conversion factor between moles and grams is given by the molar mass of gold. The molar mass of gold is 197.0 g/mol. Using this conversion factor, we can calculate:
5.00 ounces x 28.3495 grams/ounce x 1 mole/197.0 grams = 0.723 moles of gold
Therefore, there are approximately 0.723 moles of gold in 5.00 ounces.
