How to find the mass number of an isotope?What are Isotopes?Isotopes are different 'versions' of an element differing in the number of neutrons found in the nucleus. The atomic weight for an element is usually not an integer as it is the weighted averages of all the isotopes of that ...
if you know how many moles of the compound you have, you can calculate its mass. For either calculation, you need to know two things: the chemical formula of the compound and the mass numbers of the elements that comprise it. An element's mass number is unique to that element,...
Step 2:Find the number of protons of the element from the periodic table. The number of protons is equal to the atomic number of the element. Step 3:Add the number of protons found inStep 2and the number of neutrons given in the problem. This sum is the mass number of the element. ...

How to find the number of protons in an atom What is relative atomic mass? An atom has 20 electrons and 20 neutrons. What is the mass of this atom? How did Millikan calculate the mass of an electron? What is the difference between mass number and atomic mass?
A triple beam balance is a device that measures the mass of an object by comparing it with a system of three counterweights. The advantage of using this system is it allows you to measure the weight of an object extremely precisely.
Now it's time to practice your skills using the triple-beam balance. Problem 1: A block is put onto a triple beam balance. What is the mass of the object (to the closest tenth of a gram)? Remember to find the mass using a triple beam balance you must add the mass values of each...
“Discovering the nature of dark matter and its properties would help us to understand the evolution of our universe, and would be an important step forward in our understanding of the fundamental laws of nature,” Dutta says. Sarah Wells ...
