How can knowing the formula weights of the elements help you balance the equation?
The molar mass is not needed to balance a chemical reaction.You need to know the chemical formulas of reactants, the possible formulas of products, valences of elements and ions, general principles of chemical reactions, some chemical and physical properties of substances involved in the reaction.
How many moles in the compound magnesium sulfate and water?
Based on the atomic weights of the 4 relevant elements, you can convert the weight of a chemical into moles. If you do not tell us the weight, we cannot perform the conversion.
How did Mendeleyev organize the periodic table of elements?
In increasing order of atomic weights.
What are the four elements smaller than uranium?
All the elements with the atomic number under 92 has atomic weights smaller than uranium.
What is the molar mass of all ther elements?
The molar mass of any element is its atomic weight in grams. The atomic weights of the elements are found on the periodic table.
Who was the Russian chemist show a definite relationship between chemical properties and atomic weights of the elements?
Mendeleev
What is the sum of atomic mass?
I suppose that you think to atomic weights (not mass) of chemical elements and the molecular mass.
Who arrange the elements in the periodic table according to increase in atomic weights?
Dmitri Mendeleev is generally credited with the creation of the periodic table. http://en.wikipedia.org/wiki/Dmitri_Mendeleev
What is the mass of 4000 molecules of nitrogen?
Nitrogen is an element(atom), not a molecule. atomic weights are not a constant of nature and depend on the physical and chemical history of the elements. isotopes have different weights.
How did mendeleev arrange his version of the periodic table?
Mendeleev arranged his version of the Periodic Table in terms of ascending atomic weights and similar properties. Since it was first published in 1869, there have been updates and improvements.
How did Mendeleev know where to leave the spaces in his periodic table?
mandeleev didn't know spaces in the Periodic Table because he doesn't arrange it john Kepler arrange it most of mendeleev discoveries of elements are few most of other element where discover by other scientist after him in 19th century

What has the author G D Hinrichs written?
G. D. Hinrichs has written: 'The true atomic weights of the chemical elements and the unity of matter'
Why it is necessary to introduce amu unit?
The atomic mass unit is necessary to evaluate the atomic weights of chemical elements (or atomic masses of isotopes).
What was the periodic table first arranged by. How has this changed?
In 1869 Russian teacher and scientist Dmitri Mendeleev, presented a periodic table of the elements based on atomic weights. The current periodic table is arranged by the atomic numbers of the elements.
Which scientists work became the accepted explanation of atomic theory?
Modern Atomic Theory was developed by British scientist, John Dalton. His theory rested on four factors. Chemical elements are composed of atoms. Atoms in an element, are identical to the weight of the element. Atoms of different elements have different weights. To form compounds, atoms are combined in small, whole-number ratios.
Does the periodic table gives the mass number of the most common isotopes of an element?
The periodic table give the atomic numbers and the atomic weights of chemical elements.
