Question

how many moles of fluorine are contained in 116 l at stp?
mol

Explanation:

Step1: Recall molar volume at STP

At STP, 1 mole of gas = 22.4 L.

Step2: Calculate moles of fluorine

Moles = Volume / Molar volume = $\frac{116\ \text{L}}{22.4\ \text{L/mol}}$

Step3: Compute the result

$\frac{116}{22.4} \approx 5.18$

Answer:

5.18 mol
