From the following balanced equation:

[tex]2H_2(g) + O_2(g) \rightarrow 2H_2O(g)[/tex]

How many grams of [tex]H_2O[/tex] can be formed from 5.58 g [tex]H_2[/tex]?

Select the correct answer below:

A. 49.9 g
B. 0.624 g
C. 99.8 g
D. 5.54 g

Answer :

49.9 grams of H[tex]_{2}[/tex]O can be from 5.58 grams of H[tex]_{2}[/tex] from the given balanced dequation. Option A) 49.9 g is the correct answer.

To determine the amount of H[tex]_{2}[/tex]O that can be formed from 5.58 g of H[tex]_{2}[/tex], we need to use the balanced equation and stoichiometry.

From the balanced equation 2H[tex]_{2}[/tex](g) + O[tex]_{2}[/tex](g) → 2H[tex]_{2}[/tex]O(g), we can see that for every 2 moles of H[tex]_{2}[/tex], 2 moles of H[tex]_{2}[/tex]O are produced.

To calculate the number of moles of H[tex]_{2}[/tex] in 5.58 g, we divide the mass by the molar mass of H[tex]_{2}[/tex], which is 2 g/mol. Therefore, 5.58 g H[tex]_{2}[/tex] corresponds to 5.58 g / 2 g/mol = 2.79 mol H[tex]_{2}[/tex].

Since the mole ratio between H[tex]_{2}[/tex] and H[tex]_{2}[/tex]O is 1:1, the number of moles of H[tex]_{2}[/tex]O formed will also be 2.79 mol.

To convert the moles of H[tex]_{2}[/tex]O to grams, we multiply the number of moles by the molar mass of H[tex]_{2}[/tex]O, which is approximately 18 g/mol. Thus, the mass of H[tex]_{2}[/tex]O formed is 2.79 mol × 18 g/mol = 50.22 g.

Therefore, the correct answer is Option A) 49.9 g.
