ch2o and c6h12o6
it can be calculated using the formula percentage composition of N =Gram molecular mass of nitrogen in the compound/ Gram molecular mass of compound *100
((mass of element)/(mass of compound))*100
The molecular formula is C3H6 and the empirical formula is CH2. This compound is called propene or propylene, and it is a colorless gas.
The number of atoms of one element in the compound
This compound is the trioxygen diarsenic oxide (As2O3), containing 75,7442 % As and 24,2558 % oxygen.
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.
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.
Percent composition can be used to calculate the percentage of an element/compound in a mixture. From the percent composition, you can also find the empirical formula. And from the empirical formula you can find the actual molecular weight.
