Understanding the relationship between moles and atoms is an essential part of studying chemistry. In this article, we will explain how to calculate the number of atoms in a given sample if you know ...

In the world of chemistry, it’s essential to be able to work with units of measurement accurately. One such unit is the millimole (mmol), which is used to express amounts of a chemical substance. In ...

Why did they form at that time? Astronomers know from observing distant exploding stars that the size of the universe has ...

Physicists at the Massachusetts Institute of Technology (MIT) have made a groundbreaking discovery, developing a tabletop ...

If you think of a single atom as a grain of sand, then a wavelength of visible light—which is a thousand times larger than ...

A new computational method now makes it possible to calculate the forces between large molecules with unprecedented accuracy.

MIT researchers have devised a new molecular technique that lets electrons probe inside atomic nuclei, replacing massive particle accelerators with a tabletop setup. By studying radium monofluoride, ...

What color is an atom? Since atoms are smaller than the wavelength of visible light, we can’t see them directly - but they ...

Determining the number of copies of a double stranded DNA template (be it genomic DNA, plasmid or an amplified fragment) is essential for many genetic quantification applications in research and ...
