what is the volume of 0.58 moles of h2 gas at stp?

Explanation:

Step1: Recall molar - volume at STP

At STP (Standard Temperature and Pressure, 0°C or 273 K and 1 atm), 1 mole of any ideal gas occupies a volume of 22.4 L.

Step2: Set up the proportion

Let (V) be the volume of 0.58 moles of (H_2) gas. We know that (\frac{V}{n}=\frac{V_{molar}}{1\ mol}), where (n = 0.58\ mol) and (V_{molar}=22.4\ L/mol). So (V=n\times V_{molar}).

Step3: Calculate the volume

(V = 0.58\ mol\times22.4\ L/mol) (V=13.0\ L) (rounded to one decimal place)

Answer:

13.0 L
