Explanation:

$molar \: mass \: of \: iron = 56 \: g \\ 56 \: g\: are \: weighed \: by \: 1 \: mole \: of \: iron \\ 595 \: g \: will \: be \: weighed \: by \: ( \frac{595}{56} ) \: moles \\ = 10.625 \: moles \: of \: iron \\ from \: equation : \\ 1 \: mole \: of \: iron \: is \: formed \: by \: 1 \: mole \: of \: hydrogen \\ 10.625 \: moles \: will \: be \: produced \: by \: (10.625 \times 1) \: moles \\ = 10.625 \: moles \: of \: hydrogen \\ at \: s.t.p : \\ 1 \: mole \: = \: 22.4 \: litres \\ 10.625 \: moles \: = (22.4 \times 10.625) \\ = 238 \: litres \\ \\ or \: at \: r.t.p : \\ 1 \: mole \: = 24 \: litres \\ 10.625 \: moles \: = \: (10.625 \times 24) \\ = 255 \: litres$

Using Dimensional Analysis

<h3>Explanation:</h3>

<u>Step 1: Define</u>

0.75 mol SO₂

<u>Step 2: Identify Conversions</u>

[PT] Molar Mass of S - 32.07 g/mol

[PT] Molar Mass of O - 16.00 g/mol

Molar Mass of SO₂ - 32.07 + 2(16.00) = 64.07 g/mol

<u>Step 3: Convert</u>

Set up: $\displaystyle 0.75 \ mol \ SO_2(\frac{64.07 \ g \ SO_2}{1 \ mol \ SO_2})$
Multiply/Divide: $\displaystyle 48.0525 \ g \ SO_2$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 2 sig figs.</em>

48.0525 g SO₂ ≈ 48 g SO₂
