Question

What is the mass of one mole of AuCl3?

Answer 1

`303.5\text{ g/mol}`

Step-by-step explanation:

Here, we want to get the mass of one mole of AuCl3

This refers to the molar mass of AuCl3

To get this, we have to use the masses of the constituent atoms

The atomic mass of gold is 197 amu

The atomic mass of chlorine is 35.5 amu

Thus, the mass of one mole AuCl3 will be:

`\begin{gathered} 197\text{ + 3\lparen35.5\rparen} \\ 197\text{ + 106.5 = 303.5 g/mol} \end{gathered}`
