Answer:

[tex]\frac{4molPF_3}{1molP_4}[/tex]

Explanation:

Hello

In this case, given the reaction:

[tex]P_4(s)+6F_2(g)\rightarrow 4PF_3(g)[/tex]

It means that since the coefficients preceding phosphorous and phosphorous trifluoride are 1 and 4, the correct mole ratio should be:

[tex]\frac{4molPF_3}{1molP_4}[/tex]

Because given the mass of phosphorous it is convenient to convert it to moles and then cancel it out with the moles on bottom of the mole ratio.

Bes regards!
