Question

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

Explanation:

Step1: Recall STP molar volume

At STP, 1 mole of gas = 22.4 L.

Step2: Calculate moles of fluorine

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

Step3: Compute the value

$116 \div 22.4 \approx 5.1786$.

Answer:

5.18 (rounded to two decimal places) or 5.1786 (unrounded)
