Question

Solve the following problems below. Do this in a separate sheet of paper

Gold (Au) has been used to make ornamental objects and jewelry for thousands of years. Gold nuggets found in a stream are very easy to work and were probably one of the first metals used by humans. (1 mol of Gold (Au) = 196.97g). Calculate the:
Number of moles in a 95.0 g sample of a gold nugget.

Answer 1

The number of moles in a 95.0 g sample of a gold nugget is calculated by dividing the mass of the gold sample by the molar mass of gold, which gives approximately 0.482 moles of gold.

Step-by-step explanation:

To calculate the number of moles in a 95.0 g sample of a gold nugget, we need to use the molar mass of gold, which is 196.97 g/mol. The number of moles n is found by dividing the mass of the gold sample by the molar mass of gold.

The equation for this process is n = mass (g) / molar mass (g/mol).

For a 95.0 g sample of gold, the calculation would be:

n = 95.0 g / 196.97 g/mol = 0.482 moles of gold (Au)
