Knowing the relative fraction of each isotope of a particular element that occurs in nature allows you to calculate the atomic mass of that element, which, because it is an average, is not the mass of any one atom but a number that is between the heaviest and lightest isotopes pres...
Find the relative mass of any atom by adding the number of protons to the number of neutrons. Hydrogen has a relative atomic mass of 1, and carbon-12 has a relative atomic mass of 12. Isotopes of the same element have different numbers of neutrons, so you need to calculate for one spe...
Mean is the average value of the given set of observations. In statistics, we also come across different types of mean such as Arithmetic, Geometric and Harmonic mean. Leant how to find the mean here.
If it's your first encounter with chemistry, your instructor will want you to learn how to use theperiodic tableto find the atomic mass (atomic weight) of an element. This number usually is given below an element's symbol. Look for the decimal number, which is aweighted average of the ...

How to find density; What density formula is; and What affects the density of water. How to use this density calculator Here, we will guide you on putting this density calculator to good use: Enter the weight/mass of the object. To enter the mass in a different unit, click on the uni...
Brain Chemistry During Alcohol Use Like any other addictive drug, alcoholaffectsthe brain’s chemistry. When a person drinks alcohol, the drug causes their brain to release neurotransmitters responsible for signaling pleasure and reward (among other things). In the brain, alcohol increases the effects...
Wet Chemistry:Wet chemistry lab techniques include colorimetry, gravimetry, and titrimetry, which may filter, distill, or dissolve samples to extract metals. Chemical analysis is the conventional method of element analysis using laboratory beakers and flasks to manipulate a sample to identify a single...
To find the mass of a one mole of a specific molecule, add the atomic masses of each of its component atoms. You can look these up in the periodic table.
The atomic mass shown on the periodic table is an average based on how common different isotopes are in relation to each other.Finding the Atomic Mass Based on Atom Number To find how much a certain number of atoms weigh in atomic mass units, multiply the atomic mass by the number of ...
