Answer: The relative molecular mass of H4SO4 (sulfuric acid) is approximately 100.092 g/mol.
Explanation:To calculate the relative molecular mass of H4SO4 (sulfuric acid), we need to add up the atomic masses of all the atoms in its chemical formula.
The chemical formula of sulfuric acid (H4SO4) consists of the following atoms:
• 4 hydrogen atoms (H)
• 1 sulfur atom (S)
• 4 oxygen atoms (O)
The atomic masses of these elements are approximately:
• Hydrogen (H): 1.008 g/mol
• Sulfur (S): 32.06 g/mol
• Oxygen (O): 16.00 g/mol
Now, let’s calculate the relative molecular mass (also known as molar mass or molecular weight):
Relative molecular mass of H4SO4 = (4 * H) + S + (4 * O)
Relative molecular mass of H4SO4 = (4 * 1.008 g/mol) + 32.06 g/mol + (4 * 16.00 g/mol)
Relative molecular mass of H4SO4 = 4.032 g/mol + 32.06 g/mol + 64.00 g/mol
Relative molecular mass of H4SO4 = 100.092 g/mol
The relative molecular mass of H4SO4 (sulfuric acid) is approximately 100.092 g/mol.
