Understanding the Atomic Mass of Hydrogen

The atomic mass of hydrogen is a fundamental concept in chemistry, denoted by the symbol 'H' and having an atomic mass of 1.01. This value represents the average mass of a hydrogen atom, taking into account the naturally occurring isotopes of hydrogen, which are protium (1H), deuterium (2H or D), and tritium (3H or T). The atomic mass of hydrogen is a crucial parameter in calculating the molar mass of compounds that contain hydrogen.

The Molar Mass of Aluminum Hydroxide

Aluminum hydroxide, denoted by the chemical formula Al(OH)3, is a compound composed of aluminum (Al), oxygen (O), and hydrogen (H). To determine the mass of hydrogen in one mole of aluminum hydroxide, we need to calculate the molar mass of the compound. The molar mass of aluminum hydroxide can be calculated by summing the atomic masses of its constituent elements, which are aluminum (Al), oxygen (O), and hydrogen (H).

Calculating the Molar Mass of Aluminum Hydroxide

The atomic mass of aluminum (Al) is approximately 26.98 g/mol, while the atomic mass of oxygen (O) is approximately 16.00 g/mol. Since there are three oxygen atoms in one molecule of aluminum hydroxide, the total mass of oxygen in the compound is 3 × 16.00 = 48.00 g/mol. The atomic mass of hydrogen (H) is 1.01 g/mol, and since there are three hydrogen atoms in one molecule of aluminum hydroxide, the total mass of hydrogen in the compound is 3 × 1.01 = 3.03 g/mol.

Calculating the Molar Mass of Aluminum Hydroxide

The molar mass of aluminum hydroxide can be calculated by summing the masses of its constituent elements:

Molar mass of Al(OH)3 = (26.98 g/mol) + (48.00 g/mol) + (3.03 g/mol) Molar mass of Al(OH)3 = 78.01 g/mol

Determining the Mass of Hydrogen in One Mole of Aluminum Hydroxide

Since the molar mass of aluminum hydroxide is 78.01 g/mol, and the mass of hydrogen in the compound is 3.03 g/mol, we can determine the mass of hydrogen in one mole of aluminum hydroxide by dividing the mass of hydrogen by the molar mass of the compound:

Mass of hydrogen in one mole of Al(OH)3 = (3.03 g/mol) / (78.01 g/mol) Mass of hydrogen in one mole of Al(OH)3 = 0.0389 mol

However, this is not the correct answer. We need to find the mass of hydrogen in one mole of aluminum hydroxide in grams.

Calculating the Mass of Hydrogen in One Mole of Aluminum Hydroxide

To calculate the mass of hydrogen in one mole of aluminum hydroxide, we need to multiply the mass of hydrogen in the compound by the number of moles of the compound:
