To find how much gold can be recovered, you need to consider the molar mass of gold (Au) which is 196.97 g/mol and the molecular weight of AuCl3 which is 303.33 g/mol. From this information, you can set up a ratio to determine that 35g of AuCl3 contains approximately 23.15g of gold.
For this problem, the atomic mass is required. Take the mass in grams and divide it by the atomic mass. Then multiply it by Avogadro's constant, 6.02 × 1023. AuCl3= 303.5 grams5.00 grams AuCl3 / (303.5 grams) × (6.02 × 1023 atoms) = 9.92 × 1021 atoms
The molar mass of chlorine is 35.45 g/mol. From the equation, 3 moles of chlorine are needed to form 1 mole of AuCl3. Therefore, 100.0 grams of chlorine corresponds to 100.0 g / 35.45 g/mol = 2.82 moles of Cl2. This would allow the formation of 2.82 / 3 = 0.94 moles of AuCl3. Finally, the molar mass of AuCl3 is 303.33 g/mol, which means 0.94 moles of AuCl3 would be equivalent to 0.94 mol * 303.33 g/mol = 285.53 grams of AuCl3.
There are approximately 31.1 grams in 1 ounce of gold.
There are approximately 31.1 grams in one ounce of gold.
