Convert oxide wt.% into molecular proportion of each oxide. This is done by dividing the wt. % of each oxide by the molecular weight of the oxide.

How do you find the molar mass of beryllium oxide?
I don't know the method, but here is the link to the Beryllium Oxide Properties
How many grams of oxygen are in 5.75 moles of aluminum oxide?
Well to find how many grams are in moles you would eventually multiply the mole by the molar mass. The molar mass of aluminum oxide would be 101.96 ( you would find that by multiplying the atomic mass of al by 2 and o by 3 and adding them together). But the molar mass of Oxygen is just about 48 (rounded to 16 instead of 15.9994)5.75 moles of Al2O3 X 48 g oxygen/1 mole of Al2O3=276 g oxygen in 5.75 mole Al2O3
The molar mass of C3H8O2 is?
to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu) to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu)
How does the law of definite proportions explain the fact that although water and hydrogen peroxide consist of the same elements have different properties?
First find out what the law of definite proportions is. Then explain the fact that water and hydrogen peroxide consist of the same elements. Then find out if they have different or the same properties.
What is acetone's percent composition by mass?
%C= 62.0% %H2= 10.4% %O2= 27.5% To find these, you divide the molar mass of the specific element in the compound divided by the molar mass of the entire compound.

Calculate the mass percent of each element in CaCO3?
CaCO3 is the formula of the substance (calcium carbonate), which gives the information about the proportions of the different elements which make up the compound. To find the 'mass percentage' however, it is necessary to use the molar mass of each element. Molar mass of Calcium = 40.08 g/mol Molar mass of Carbon = 12.01 g/mol Molar mass of Oxygen = 16.00 g/mol To find the percentage mass of one of these elements, divide the molar mass of the element by the total molar mass of the compound (add them all up, using oxygen three times), then multiply by 100%. Molar mass of CaCO3 = 40.08 +12.01 + 3*16.00 = 100.09 g/mol % Calcium = 40.08/100.09 * 100% = 40.0% % Carbon = 12.01/100.09 * 100% = 12.0% % Oxygen = (3*16.00)/10.09 * 100% = 48.0%

How do you find the molar mass of ZnF2?
The atomic weight of zinc is: 65,38 The atomic weight of fluorine is: 18,998 403 2 The molecular mass of zinc difluoride is by consequence: 65,38 + 2 x 18,998 403 2. And M= 103,406 g/mol (for the anhydrous molecule)

What is the melting point of baking soda?
The molar massforNa, Sodium, is 23H, Hydrogen, is 1C, Carbon, 123 Oxygen, 48.84 is the Molar MassAdd all of the elements and you get the molar mass of Baking Soda. You can find the molar mass for each element on the periodic table. I rounded up on all of the elements.
How do you use proportions using cross multiplication to find 2.80?
2.80 is 2.80: you do not need to ise proportions or anything to "find" it!

How find percent compsotion of oxygen in Na2O?
To find the percent composition of oxygen in Na2O, find the total molar mass of the compound. Then, divide the molar mass of oxygen by the molar mass of the compound, and multiply by 100% to get the percent oxygen.
