It would 47.7 because you would have to both minus the number together.
Answer:
387 g/mol
Explanation:
The molar mass is a ratio comparing a substance's mass and molar value. The specific ratio looks like this:
Molar Mass (g/mol) = mass (g) / moles
You can plug the given values into the ratio to find the molar mass.
Molar Mass = mass / moles
Molar Mass = 0.406 g / 0.00105 mol
Molar Mass = 387 g/mol
Answer:
FeSO₄ + 2NaOH → Fe(OH)₂ + Na₂SO₄
Explanation:
The equation for the reaction is:
FeSO₄ + 2NaOH → Fe(OH)₂ + Na₂SO₄
Dissociation of each compound
FeSO₄ → Fe²⁺ + SO₄⁻²
NaOH → Na⁺ + OH⁻
Fe(OH)₂ → Fe²⁺ + 2OH⁻
Na₂SO₄ → 2Na⁺ + SO₄⁻²
