# Session Digital: Volumes 💨

Representing 3D molecules in 2D

What color is used to show a carbon atom?

What color is used to show a nitrogen atom?

What color is used to show an oxygen atom?

What color is used to show a hydrogen?

What color is used to show a sulphur?

What color is used to show a chlorine?

Draw the full structural formula of these molecules. Click and drag to rotate them so you can see better.

See the [Help] tab for the answers as well as what these molecules do.

Molecular Formula

Deduce the molecular formula of these molecules. If you have not completed the previous puzzle I suggest you to do them first.

If we approximate a water molecule as a sphere, its diameter would be 2.75 Å. What is its volume?

How many water molecules can fit into 1 dm3?

# Homework

A new Anki deck for molecular formula had been added to the Google Drive. Install it, and keep doing your Anki decks.

Read section 3.1 (The Periodic Table) in your textbook, complete the exercise, and mark your answers. Complete by (Sun) 21:00. This should take no more than 20 minutes.

This is an intentionally light week. Use this time to catch up on what you have
