We were given 78.54 grams of chromium and asked to find the mass of carbon with the same number of atoms to it. We will need the molar mass of...
Atoms of different elements have different atomic numbers. For example, all carbon atoms have the atomic number of 6, whereas all atoms of Oxygen have 8 protons in their nucleus. What is Mass Number? The number of protons and neutrons combine to give us the mass number of an atom. It is...
The relative mass (m) is a dimensionless number which is defined as the mass of an atom, a molecule or an ion divided by 1/12th of the mass of the 12C carbon atom. The charge number (z) is the total charge on an ion divided by the elementary charge (e), 1.602177 × 10− 19...
Another way to express the atomic mass of carbon-12 is using the Dalton (Da or u), which is the unified atomic mass unit. Therefore, the atomic mass of carbon-12 is 12 amu or 12 Da. Related calculators Number of protons (Z) Number of neutrons (N) Atomic mass Atomic mass (...
Change the unit first before you enter a number. That's it! The volume to mass calculator will find the result in less than a second! Here are the products and their densities available in our calculator: Food: Water — 1,000 kg/m3 Milk — 1,030 kg/m3 Flour Buckwheat — 660 kg...

The studied alkanes had a fixed backbone of three carbons and different kinetic diameters depending on the number of methyl groups on the central carbon atom. The studied zeolites had 12-, 10-, or 8-member ring (MR) entrances to the intracrystalline cavities. Only propane was found to pass...
