Answer:
![Cu_{3}P](https://tex.z-dn.net/?f=Cu_%7B3%7DP)
Explanation:
usually, the first step is to calculate the moles but since that is already given in the question we can move onto the next step
<em><u>least molar ratio:</u></em>
<em>Cu = </em>
= 3
P =
= 1
thus, empirical formula = ![Cu_{3}P](https://tex.z-dn.net/?f=Cu_%7B3%7DP)
