Molarity
of the solution is defined as the number of moles of solute dissolved per litre (dm 3 ) of the solution. It is denoted by the symbol M. Measurements in Molarity can change with the change in temperature because solutions expand or contract accordingly. In terms of weight, mol..

Mass - Mass is the quantity of matter in the body. Mass is measured by finding out the force needed to change the way the object moves. The greater the force needed, greater the mass of the object. If you push a book, it moves faster than if you push a car wi..
Mass
A proton is actually a hydrogen atom, which has lost its electron. Since the mass of an electron is small, the mass of a proton is equal to the mass of a hydrogen atom. As the mass of hydrogen atom is 1 a.m.u., the relative mass of a prot..
Mass
The SI unit is kilogram. 1 kg is defined as the mass of a platinum-iridium cylinder kept at the International Bureau of W and M at Sevres, France, established in 1887. The atomic structure of mass is yet to be develop..
Atomic Mass of Elements
Experimentally it is determined that the mass of an atom is very small ranging from 1.7 x 10 - 2 4 g to about 4.0 x 10 - 2 2 g. These small masses are terribly impractical to work with. Thus, it became necessary to reduce the atomic masses into simple figures..

The atomic mass of an element is a relative quantity and is the mass of one atom of the element relative to the mass of one carbon-12 atom. Thus,Relative atomic mass (RAM) of an element is the number of times ..

In many instances, the most convenient unit for specifying the amount of a substance is the mole, where 1 mole = 6.023 x 10 2 3 elementary units of any substance. Thus, 1 mole of aluminum means 6.023 x 10 2 3 atoms (the atom being the elementary unit), and 1 mol of alu..
Molar Volume
One mole of any gas at STP will have a volume of 22.4 L. This is called molar volume. The molar volume [22.4 L at STP] plays a vital role in stoichiometric calculations because it is the link between volume and mass in reactions involving gas..

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 ..

Tutor Vista perceived the math apps well and I enjoyed getting to work with Tutor Vista - Savannah
Better than great. That was the best 45 minutes i have spent on here. We got a lot done and i have a better understanding of the material. Thanks
Tutor is an excellent. I would say this tutor is an asset of Tutor Vista.. Excellent Job!!!!!!!
The tutor remembered me from last week and noted my improvement. This is simply amazing :)
