Final answer:
To determine the number of moles in 150.8 g of H₂SO₄, divide the mass by the molar mass (98.02 g/mol), resulting in approximately 1.54 moles.
Step-by-step explanation:
To calculate the number of moles in 150.8 g of H₂SO₄, you need to use the molar mass of H₂SO₄. The molar mass of sulfuric acid (H₂SO₄) is 98.02 g/mol. According to the formula for the number of moles, which is mass (in grams) divided by molar mass (in g/mol), the calculation would be:
Number of moles = Mass of substance (g) / Molar mass (g/mol)
In this case, the calculation would be:
Number of moles = 150.8 g / 98.02 g/mol
This gives:
Number of moles ≈ 1.54 mol
Therefore, there are approximately 1.54 moles in 150.8 grams of H₂SO₄.
