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}

A block has a mass of 30g and dimensions of 1.5cm by 4.8cm by 2.3cm. Calculate the density (round to TWO sig figs).
adelina 88 [10]

Answer:

1.8g/cm³

Explanation:

Density is defined as the ratio of the mass of a substance and the space this subtance occupies. It is usually given in g/cm³.

The mass of the block is 30g.

The volume this mass occupies is 1.5cm × 4.8cm × 2.3cm = 16.56cm³.

The density is:

30g / 16.56cm³ =

<h3>1.8g/cm³</h3>
