Take 1.45 wt% oxide as an example.
To remove the oxide component first you must work out the Ti component:
1.45 wt% oxide x 0.6 = Ti (wt%)
because Ti in TiO2 makes up 60% its formula mass:
47.87 / 79.87 = ~0.6 Ti
Thus
1.45wt% TiO2 = 0.87 wt% Ti
To calculate the atomic weight of an element with multiple isotopes, you multiply the mass of each isotope by its relative abundance (as a decimal), then sum the products. The result is the atomic weight of the element, which is a weighted average of the masses of its isotopes based on their abundance in nature.
A) Convert each mass to grams. B) Divide each molar amount by the ...Top answer: B) Divide each molar amount by the smallest molar amount
The element with an atomic weight of 121.75 is antimony, with the chemical symbol Sb.
((mass of element)/(mass of compound))*100
Sulfur (32.065)
How can I convert atomic percent to weight percent for example TiC -45%atomic C convert to weight percentage?
To convert from mol percent to weight percent, we need to know the molecular weights of the substances involved. Without this information, we cannot accurately convert 0.0141 mol percent to weight percent.
Oxygen
Oxygen
Multiply the mass fraction by 100.
Iodine represents less than 0.01 percent of body weight.
First off you multiply moles by 1000 to convert to millimoles. Next you multiply by the molecular weight (found as the bigger figure on the element on the periodic table).
You cannot without information on the densities of the two substances.
To convert from mg to mEq, divide the amount of mg by the atomic weight of the element and multiply by the valence of the element. For sodium, the atomic weight is 23 and the valence is 1. Therefore, to convert 290mg of sodium to mEq: (290 mg / 23) x 1 = 12.6 mEq.
Atomic percent is based on the number of atoms in a sample. So if the sample has x number of oxygen atoms and x number of iron atoms it would report 50% oxygen and 50% iron (atomic percent). Weight percent is based on the mass of the elements detected. So if we used the above example and reported the results as weight percent we would get 22.3% oxygen and 77.7% iron. Weight percent takes into consideration the mass or atomic weight of the elements and not just the number of atoms. Most people use weight percent although for chemistry atomic percent may be more useful.
To calculate the atomic weight of an element with multiple isotopes, you multiply the mass of each isotope by its relative abundance (as a decimal), then sum the products. The result is the atomic weight of the element, which is a weighted average of the masses of its isotopes based on their abundance in nature.
The percent composition by mass of a compound is determined by dividing the mass of each element in the compound by the total mass of the compound, then multiplying by 100 to get the percentage. This calculation gives the proportion of each element in the compound by mass.
