# Calculate the mass percent of titanium in the mineral ilmenite, FeTiO3. What mass of ilmenite (in grams) is required if you wish to obtain 750 g of titanium?

Interpretation Introduction

Interpretation:

The mass percent of titanium in FeTiO3 and the mass of FeTiO3 required to obtain 750g  of titanium metal are needed to be calculated.

Concept introduction:

• Mass percent of elements of a compound is the ratio of mass of element to the mass of whole compound and multiplied with hundred.
• Equation for finding molar mass from mass of a molecule and number moles is,

Molarmass=MassingramsNumberofmoles

• Molar mass of a molecule can be calculated from its molecular formula by taking the sum of atomic masses of all the elements present in it.
Explanation

The molar mass of FeTiO3 is 15.71g/mol .

Mass percent of elements of a compound is the ratio of mass of element to the mass of whole compound and multiplied with hundred.

Therefore,

The mass percent of Ti in FeTiO3 is,

Â Â Â Â 47.867gâ€‰Ti151.71gâ€‰FeTiO3â€‰Ã—100%â€‰=â€‰31.55%â€‰Ti

Mass percent of an element means, 100g of compound contains that mass percent of an element in grams
