89.1% Au
The molar mass of Au2O3 is 2(196.97) + 3(16.00) = 441.94 g/mol
The mass percent of Au is therefore 2(196.97) / 441.94, which is 393.94/441.94 = 0.891 —> 89.1%

<h3>How are units labeled?</h3>
Use standardized unit abbreviations. For clarity, place units of before nonstandard units, such as (a) (units of a). When separating the components of a compound unit, use short spaces rather than hyphens, dots, or other symbols. For numbers on figure axes, use superscripts, multiplication signs, and powers of 10.
<h3>What is label in math means?</h3>

Answer:
Higher pH (more alkaline)
Explanation:
The pH scale measures on a scale of 0 to 14 the acidity or basicness of whatever is being tested.
The lower the pH, the more acidic it will be. Acids are scaled as being anything having a pH of lower than 7.
The higher the pH, the more alkaline (or basic) it will be. Bases are scaled as being anything having a pH of higher than 7.
Substances that are at a pH of 7 are considered neutral, like water (H2O)
