Explanation:
A Material Safety Data Sheet (MSDS) is a document with a description about potential hazards (health, environment, reactivity, etc.), physical properties, how to storage and how to manipulate and work safely with a given chemical product or substance. These kind of documents are standarized to a correct interpretation of final user. When someone purchased a chemical, chemical supply companies must provide the respective MSDS. However this kind of label are not legally required to be accurate.

Answer:
0.1313 g.
Explanation:
- It is known that at STP, 1.0 mole of ideal gas occupies 22.4 L.
- Suppose that hydrogen behaves ideally and at STP conditions.
<u><em>Using cross multiplication:</em></u>
1.0 mol of hydrogen occupies → 22.4 L.
??? mol of hydrogen occupies → 1.47 L.
∴ The no. of moles of hydrogen that occupies 1.47 L = (1.0 mol)(1.47 L)/(22.4 L) = 6.563 x 10⁻² mol.
- Now, we can get the no. of grams of hydrogen in 6.563 x 10⁻² mol:
<em>The no. of grams of hydrogen = no. of hydrogen moles x molar mass of hydrogen</em> = (6.563 x 10⁻² mol)(2.0 g/mol) = <em>0.1313 g.</em>
