Atomic and Molecular Masses
It is known that the atomic mass of an element/compound is not the mass of one atom or molecule of the said element/compound because they occur as a mixture of isotopes. As the atomic and molecular masses are expressed on a relative ..
Correction of Atomic Masses
Mendeleev's periodic table helped in correcting the atomic masses of some of the elements, based on their positions in the periodic table. For example, atomic mass of beryllium was corrected from 13.5 to 9.0. Atomic masses of indium, gold..

Gram Atomic Mass (GAM)
The atomic mass of an element expressed in grams is called the gram atomic mass of an element. It is also called gram atom. Example: The gram atoms present in 46 grams of sodi..
Relative atomic mass
The atomic mass of an element is a relative quantity and is the mass of one atom of the element relative to 1/12 the mass of one carbon-12 atom. Thu..
Atomic mass unit (u)
One amu or u is used as the unit of mass in atomic physics. Mass of a C 1 2 atom is 12 atomic mass units. One u is defined as 1/12 t h of the mass of one C 1 2 atom. 1 atomic mass unit = 1 u =..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
Tutor was excellent, asnwered the question rapidly and provided the information I needed to understand the problem.
Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
I like the way this tutors double check the work with me and took time to explain each detail. It really helped me to better understand - Harry
