With the molecular formula Au2Cl6, the name gold trichloride is a simplification, referring to the empirical formula, AuCl3. The Roman numerals in the name indicate that the gold has an oxidation state of +3, which is common for gold compounds
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
Gold(III) chloride has the chemical formula AuCl3.
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
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.

Silicon's oxidation number is +4.Oxygen's oxidation number is -2
The oxidation number of nitrosyl (NO) is +1. Nitrogen typically has an oxidation number of -3, and oxygen typically has an oxidation number of -2. In NO, nitrogen has a -3 oxidation number and oxygen has a -2 oxidation number, leading to an overall oxidation number of +1 for the nitrosyl ion.
