Question

Can 750 mL of water dissolve 0.60 mol of gold(III) chloride (AuCl3)?

Answer 1

Yes

Step-by-step explanation:

1. Mass of 0.60 mol of AuCl₃

`\text{Mass} = \text{0.60 mol} * \frac{\text{303.33 g}}{\text{1 mol}} = \text{184 g}`

2. Mass of AuCl₃ in 750 mL

The solubility of AuCl₃ is 68 g/100 mL.

In 750 mL of water, you can dissolve

`\text{Mass of AuCl}_(3) = \text{750 mL} * \frac{\text{68 g}}{\text{100 mL}} = \text{510 g AlCl}_(3)`

∴ Yes, 750 mL of water can dissolve 0.60 mol of AuCl₃.
