Differences between Mass and Weight
Mass Weight 1 . It is the amount of matter contained in an object 2 . The mass of a body is constant throughout the universe 3 . Mass can never be equal to zero 4 . Mass is a scalar quantity 5 . SI unit of mass is kg 1..
Atomic Mass Unit Scale
The scale in which the relative atomic masses of different atoms are expressed is called atomic mass unit scale. Atomic masses are not expressed as whole numbers because natural elements are mixtures of two or more i..

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 ..

Question 21 - Question: What is the mass of 0.2 mole of lead nitrate? (N=14, O=16, Pb=207). Answer: Gram molecular weight of Pb(NO 3 ) 2 = 207 + (2 x 14) + 2(16 x 3) = 207 + 28 + 96 = 331 1 mole of Pb(NO 3 ) 2 is 331 g Therefore 0.2 mole of Pb(NO 3 ) 2 is 331 x 0.2 = 66.2..
Mass of the Atom
Experiments have determined that the mass of an atom is very small, ranging from 1.7x10 -24 g to about 4.0x10 -22 g. It is very difficult to accurately weigh a bunch of atoms, as they are extremely light, small, and invisible; they weigh too little for us to express th..
Atomic Number and Atomic Mass
The nuclei of atoms is made up of protons and neutrons. These two components of the nucleus are referred to as nucleons. The electrons occupy the space outside the nucleus. Since an atom is electrically neutral, the number of protons in the nucleus is exactly equal to the number..

Explained everything so well and did everything quickly.Amazing tutoring. My most favourite. Helped me a lot! :D
Tutors are AMAZING, and They helped me understand every single part of the problem and because of the way they explained everything, i had no questions to ask. It was a learning experience to remember. :)
My daughter is in 9th grade and I was having a hard time helping her. I am finding TutorVista very helpful. I don't want my daughter to think she knows more than her Mom :-) Thank you all - Megan
We had a very good debate about the pieces of an equation in standard form. Wonderful session. I enjoyed the session.
