Answer:

A single element or many elements  

Step-by-step explanation:

A molecule consists of <em>two or more atoms</em> of the same or different elements that are bound together.

Examples of molecules are O₂, H₂O, CH₂O, and C₂H₃OCl.

Answer: Option (a) is the correct answer.

Explanation:

When two or more atoms are chemically combined together then the product formed is known as a molecule.

These atoms can be bonded through either covalent or ionic bonds.

For example, a water molecule consists of two hydrogen atoms combined with an oxygen atom. Chemical formula of water is H_{2}O.

Thus, we can conclude that an element can be made of many elements.

MULTIPLE CHOICE<br> What is the molality (m) of 3.5 mol of sugar in 2.5 kg of water?
otez555 [7]

The molality of the solution is 1.4 moles per kilogram (molal).

The molality of the solution is equal to the number of moles of sugar (solute) divided by the number of kilograms of water (solvent). Hence, the molality is determined below:

m = \frac{3.5\,mol}{2.5\,kg}

m = 1.4\,\frac{mol}{kg}

The molality of the solution is 1.4 moles per kilogram (molal).
