What is the volume of one water molecule in liquid?
« on: May 31, 2013, 09:18:34 PM »
What is the volume of one water molecule in liquid water if it can be assumed that the liquid's volume is filled with water molecules?

The answer is approximately 30 Å^3 (where Å is the measurement Ångstrom)

Can somebody explain how to get to this answer?

Start with the density of water.

1000 kg/m^3?

Now, this is the amount of mass of water for a specified volume.  You need the amount of volume for 1 molecule of water.

There are two missing pieces of information to connect these two concepts.  What are they?
