What is the mass percent of oxygen (o) in so2? chemistry’s

49.92% is the mass percent of oxygen (O)in sulfur dioxide.

Explanation:

Atomic mass of oxygen = 16 g/mol

Number of oxygen atoms in sulfur dioxide molecule = 2

Molar mass of sulfur dioxide =16 g/mol+ 16 g/mol + 32.1 g/mol= 64.1 g/mol

Percentage of oxygen in sulfur dioxide:

49.92% is the mass percent of oxygen (O)in sulfur dioxide.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
