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 convert weight percent of an element to weight percent of its oxide, you need to consider the molar mass of the element and the oxide. Calculate the atomic ratio of the element to oxygen in the oxide, then adjust the weight percent accordingly. For example, to convert the weight percent of iron (Fe) to iron oxide (Fe2O3), you would use the molar masses of Fe and Fe2O3 to determine the conversion factor.

How do you calculate the atomic weight of a chemical element that has two or more isotopes?
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.
What steps should be used to determine the empirical formula of a compound from its mass percent composition?
Convert the mass percent composition to grams. Convert the grams to moles for each element. Divide each element's moles by the smallest number of moles to get the mole ratio. Write the empirical formula using the whole number ratio obtained.
What is the formula for the percent by mass of a compound?
((mass of element)/(mass of compound))*100
What element has 121.75 as it's atomic weight?
The element with an atomic weight of 121.75 is antimony, with the chemical symbol Sb.
What is the element to this atomic weight 32?
The element with atomic weight 32 is sulfur (S).
How do you converting from atomic percent to weight percent?
How can I convert atomic percent to weight percent for example TiC -45%atomic C convert to weight percentage?
Convert 0.0141mol percent to weight percent?
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.
By weight 65 percent of you is what element?
Oxygen
By weight 65 percent of you in what element?
Oxygen
How do you convert mass fraction to weight percent?
Multiply the mass fraction by 100.
How do you convert moles to milligrams of an element?
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).
What element represents less than 0.01 percent of body weight?
Iodine represents less than 0.01 percent of body weight.
How do you convert percent weight to percent volume for soil and bentonite mix?
You cannot without information on the densities of the two substances.
How do you convert 290mg sodium to mEq?
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.
What is the difference between atomic percent and weight percent?
Atomic percent refers to the percentage of atoms of a specific element in a compound, while weight percent is the percentage of the total weight of a compound that is due to a specific element. Atomic percent is based on the number of atoms, while weight percent is based on the mass of the elements.
How do you calculate the atomic weight of a chemical element that has two or more isotopes?
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.
How is the percent composition by mass determined?
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.
