Answer :
Final answer:
151 grams of SO₂ is approximately equal to 2.359 moles.
Explanation:
To determine the number of moles, we can use the equation:
moles = mass (g) / molar mass (g/mol)
The molar mass of SO₂ is calculated by multiplying the atomic mass of sulfur (32.06 g/mol) by the number of sulfur atoms in one molecule (1), and adding it to the product of the atomic mass of oxygen (16.00 g/mol) and the number of oxygen atoms in one molecule (2). Therefore, the molar mass of SO₂ is 64.06 g/mol.
Now, plugging in the values, we have:
moles = 151 g / 64.06 g/mol ≈ 2.359 moles.
Therefore, 151 grams of SO₂ is approximately equal to 2.359 moles.
