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) (3 points)
Answer
Explanation:
Step1: Set up the conversion
We know that 1 mole of gas at STP occupies 22.4 L. Let $n$ be the number of moles of He. We use the proportion $\frac{n}{1}=\frac{500}{22.4}$.
Step2: Calculate the number of moles
$n=\frac{500}{22.4}\approx22.3$ moles.
Answer:
22.3 moles
