For the reaction p4+6cl2 yields 4pcl3, determine how many moles of cl2 would be needed to react with 3 moles of p4 to entirely use up all phosphorous.

Explanation:

Hello,

In this case, the undergoing chemical reaction is:

In such a way, if 3 moles of P₄ are reacting, the needed moles of Cl₂ to completely consume them turn out:

This is done by realizing that 1 mole of P₄ needs 6 moles of Cl₂ to take the reaction to completion.

Best regards.
