Answer to Question #301484 in Chemistry for Shane

Question

The presence of SO² in the atmosphere causes acid rain. What percentage of sulfur is present in S0²(Molar mass=64.07 g/mole)?

Answer 1

Solution:

The molar mass of SO₂ is 64.07 g/mol

One atom of sulfur (S) has a mass of 32.07 amu

One atom of oxygen (O) has a mass of 16.00 amu

%S = (Atomis mass of S / Molar mass of SO₂) × 100%

Therefore,

%S = (32.07 / 64.07) × 100% = 50.05%

%S in SO₂ = 50.05%

Answer: The percentage of sulfur (S) in SO₂ is 50.05%
