3. PMG403 On planet Exwizee, it is known that __ The molar mass of element X is 80.22g/mol The molar mass of element Y is 36.66g/mol. The molar mass of element Z is 56.90g/mol. Determine the molar mass of the compound having the formula XY_(2)Z_(3)

To determine the molar mass of the compound $XY_{2}Z_{3}$, we need to calculate the molar mass of each element in the compound and then multiply it by the number of atoms of that element in the compound.<br /><br />Given information:<br />- The molar mass of element X is $80.22g/mol$<br />- The molar mass of element Y is $36.66g/mol$<br />- The molar mass of element Z is $56.90g/mol$<br /><br />Step 1: Calculate the molar mass of the compound $XY_{2}Z_{3}$.<br />Molar mass of $XY_{2}Z_{3}$ = (Molar mass of X) + 2 × (Molar mass of Y) + 3 × (Molar mass of Z)<br />Molar mass of $XY_{2}Z_{3}$ = $80.22g/mol + 2 × 36.66g/mol + 3 × 56.90g/mol$<br />Molar mass of $XY_{2}Z_{3}$ = $80.22g/mol + 73.32g/mol + 170.70g/mol$<br />Molar mass of $XY_{2}Z_{3}$ = $304.24g/mol$<br /><br />Therefore, the molar mass of the compound $XY_{2}Z_{3}$ is $304.24g/mol$.
