Question

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

Explanation:

Step1: Recall STP molar volume

At STP, 1 mole of gas = 22.4 L

Step2: Calculate volume

Volume = moles × molar volume = 0.58 mol × 22.4 L/mol

Step3: Compute result

0.58 × 22.4 = 13.0 L (rounded to two significant figures)

Answer:

13.0 L
