Guida verificata passo dopo passo1
Identify the empirical formula given: \(S_1O_3\), which means the simplest whole-number ratio of sulfur to oxygen atoms is 1:3.
For each molecular formula option, determine the ratio of sulfur to oxygen atoms by dividing the subscripts by their greatest common divisor (GCD) to find their empirical formula.
Compare the empirical formula of each molecular formula option to the given empirical formula \(S_1O_3\) to see which one matches.
For example, take the molecular formula \(S_2O_6\): divide both subscripts by 2 to get \(S_1O_3\), which matches the empirical formula given.
Conclude that the molecular formula whose empirical formula matches \(S_1O_3\) is the correct answer.
