Answer 1

Answer on Question #59243 - Chemistry - Inorganic Chemistry

**Task:**

How many moles are present in 1 g of gold?

**Solution:**

Gold is a chemical element with symbol Au.

The molar mass of Au is 196.97 g/mol.

We find the amount of Au:

$$n(Au) = \frac{m(Au)}{M(Au)}.$$

Then,

$$n(Au) = \frac{1g}{196.97 \frac{g}{mol}} = 0.005 \text{ mol}.$$

**Answer:**

$$n(Au) = 0.005 \text{ mol}.$$
