Multiple Choice 10 points What is the molar mass of AuCl_(3) 96g/mol 232.5g/mol 130g/mol 303.3g/mol

The molar mass of $AuCl_{3}$ is $303.3g/mol$.<br /><br />Explanation:<br />The molar mass of a compound is the sum of the molar masses of its constituent elements. In this case, $AuCl_{3}$ consists of one gold (Au) atom and three chlorine (Cl) atoms.<br /><br />The molar mass of gold (Au) is approximately $197g/mol$, and the molar mass of chlorine (Cl) is approximately $35.5g/mol$.<br /><br />To calculate the molar mass of $AuCl_{3}$, we need to multiply the molar mass of chlorine by 3 (since there are three chlorine atoms) and add it to the molar mass of gold:<br /><br />Molar mass of $AuCl_{3}$ = Molar mass of Au + 3 × Molar mass of Cl<br />= $197g/mol + 3 × 35.5g/mol$<br />= $197g/mol + 106.5g/mol$<br />= $303.5g/mol$<br /><br />Therefore, the molar mass of $AuCl_{3}$ is $303.5g/mol$.
