11.) a storage tank with a volume of 500. l contains how many moles of he at stp? (conversion factor 22.4 l = 1 mole at stp)

11.) a storage tank with a volume of 500. l contains how many moles of he at stp? (conversion factor 22.4 l = 1 mole at stp)

Answer

Explanation:

Step1: Identify the conversion - factor

We know that 1 mole of gas at STP occupies 22.4 L.

Step2: Calculate the number of moles

Let $n$ be the number of moles. We use the formula $n=\frac{V}{V_m}$, where $V = 500\ L$ (volume of the tank) and $V_m=22.4\ L/mol$ (molar - volume at STP). So $n=\frac{500}{22.4}$. $n=\frac{500}{22.4}\approx22.3$ moles

Answer:

Approximately 22.3 moles
