madam [21]

Answer:

0.214 L

Explanation:

Step 1: Write the balanced equation

This is a single displacement reaction.

Zn(s) + 2 HCl(aq) ⇒ ZnCl₂(aq) + H₂(g)

Step 2: Calculate the moles corresponding to 0.625 g of Zn

The molar mass of Zn is 65.38 g/mol.

0.625 g × 1 mol/65.38 g = 9.56 × 10⁻³ mol

Step 3: Calculate the moles of H₂ produced from 9.56 × 10⁻³ moles of Zn

The molar ratio of Zn to H₂ is 1:1. The moles of H₂ produced are 1/1 × 9.56 × 10⁻³ mol = 9.56 × 10⁻³ mol.

Step 4: Calculate the volume occupied by 9.56 × 10⁻³ moles of hydrogen

Assuming standard pressure and temperature, 1 mole of hydrogen occupies 22.4 L.

9.56 × 10⁻³ mol × 22.4 L/1 mol = 0.214 L
