In this way Einstein was able to determine the size of atoms, and how many atoms there are in a mole, or the molecular weight in grams, of a gas.

This is the molecular structure of adenine.

The nearly neutral theory of molecular evolution is a modification of the neutral theory of molecular evolution that accounts for slightly advantageous or deleterious mutations at the molecular level.

You know what the molecular structure is.

My favorite moving molecular lab.

Let's say I took some molecular hydrogen, it's in a gaseous state, and I were to combust that with some molecular oxygen.

This is how you work at the molecular scale.

And we've been given 1 mole of the oxygen molecule.

I mean, big piece at the molecular level.

And the same thing is true for the molecular oxygen.

It s very hard to explain this by molecular recognition.

And so that is what is cooling you down at a molecular level.

It's very hard to explain this by molecular recognition.

So I started to educate myself on this molecular level.

The molecular chlorine has broken up into two chlorine atoms.

Gel permeation chromatography is used to determine the number average molecular weight, weight average molecular weight, and polydispersity.

The mean molecular mass of air is 28.97 g mol.

Each has a molecular weight of approximately 50,000 Daltons.

(Laughter)

It has the molecular formula C14H14N2.HCl and a molecular weight of 246.73 g mol.

And we combine that with some oxygen, molecular oxygen, it's also a gas.

We combine that with six moles of molecular oxygen.

Because it's on this molecular level things change and they act different.

And in 2001, the cause of their deficits, a mutation in a molecule known as FoxP2, was found.

But in the process, for every mole of molecular oxygen, if you have two moles of molecular hydrogen I'm just making sure the equation is balanced you're going to produce two moles of H2O plus a ton of heat.

Many higher molecular weight amines are, biologically, highly active.

A molecular sieve can adsorb water up to 22 of its own weight.

The quality of the sample is sufficient for research on molecular biology.

And I thought molecular weight sounded much less nerdy than molar mass.

In contrast, molecular orbital theory has orbitals that cover the whole molecule.

And the important thing is, no matter the notation, as long as you can figure out the exact molecular structure.

But through science, we do have a fairly good idea of what's going on down at the molecular scale.

Plus one oxygen atom, so I could say one half of molecular oxygen.

And when you strip off the electrons and the hydrogens, you're just left with molecular oxygen.

Not just about its genetics and molecular biology, but up here in the meat end of the scale.

We could say that we started off with two moles of molecular hydrogen.

They can bond with each other and form molecular chlorine again.

The connection is broken.

The minimum size is greater than the maximum size.

And for molecular programming, the question is how does your cell phone know when to stop growing?

He believed the rays to consist of streams of particles of ordinary molecular magnitude.

They understood her breast cancer at the molecular level they had no need to touch her breasts.

And I had a telephone call from Robert Lue at Harvard, in the Molecular and Cellular Biology Department, a couple of years ago.

So the hydrogen protons and the electrons of H2O are stripped away and you're just left with molecular oxygen.
