It tells you what the substance is made of.
Not completely. The empirical formula of a substance can be determined from its percent composition, but a determination of molecular weight is needed to decide which multiple of the empirical formula represents the molecular formula.
The first step to determine the formula of a new substance is to determine the elements present in the substance through experimentation or analysis. Once the elements are identified, the next step is to determine the ratio of atoms of each element in the substance to establish the chemical formula.
Sulfur is an element, a pure substance, it is 100% sulfur.
A substance has a specific chemical composition while mixtures contain more than one substance.
A pure substance has a fixed and uniform composition.
The molecular formula of the compound can be calculated from the composition of element in a compound. The next steps are involved in the calculation of percentage of every element in a compound.
a substance
It tells you how much of a molecule is made up of each element. - APEX
The percent composition of lithium in LiOH is: 29,21 %.
Can you be more specific? Percent composition is usually the percent of an element in a compound.
No. In a physical change, the substance maintains its chemical composition.
