What is the empirical formula for a compound if a sample contains 1. 0 g of S and 1. 5 g of O? SO SO3 S2O2 S2O3.

Tcecarenko [31]

The empirical formula of the given compound is $\bold{SO_3}$ .

The correct option is B.

<h3>What is an empirical formula?</h3>

The empirical formula of a chemical compound is the simplest whole-number ratio of atoms contained in the substance.

Given,

1.0 g of S

1.5 g of O

To calculate the empirical formula, we will divide the masses of the elements by their atomic weight.

For sulfur

$\bold{\dfrac{1.0}{32} =0.03125\; mol}$

For oxygen

$\bold{\dfrac{1.5}{16} =0.09375\; mol}$

Now, divide the greater value of mole came by the smaller value

$\bold{\dfrac{0.09375\; mol}{0.03125\;mol} = 3}$

Thus, the empirical formula for the given compound is 1 for S and 3 for O

$\bold{SO_3}$
