What is the mole ratio of S_(2) (wanted) to Al_(2)S_(3) (given)? 4:3 6:10 3:2 2:5

To determine the mole ratio of $S_{2}$ (wanted) to $Al_{2}S_{3}$ (given), we need to look at the balanced chemical equation for the reaction between $Al_{2}S_{3}$ and another substance to produce $S_{2}$.<br /><br />The balanced chemical equation for the reaction is:<br />$2Al_{2}S_{3} + 3S_{2} \rightarrow 6Al + 6S$<br /><br />From the equation, we can see that the mole ratio of $S_{2}$ (wanted) to $Al_{2}S_{3}$ (given) is 3:2.<br /><br />Therefore, the correct answer is $3:2$.
