Can you Calculate the empirical formula of the compound made from 43.4 percent Na 11.3 percent C and 45.3 percent O by mass enter the empirical formula?
Crazygal992
Firstly divide percentages by molar mass of that element
Na
43.4/23=1.9
C
11.3/12.01=0.94
O
45.3/16=2.83
Then divide the result of the first step by the smallest answer
Na
1.9/.94=2
C
.94/.94=1
O
2.83/.94=3

What is the Empirical formula of the compound that is 52.7 percent K 47.3 percent Cl?
KCl
Can the empirical formula be used to calculate the percent composition of a compound?
The empirical formula is the simplest ratio of the elements within a compound. Therefore, it can be used to calculate the percentage of an element within a compound. For example, the empirical formula for sodium chloride is NaCl. From this, we can see that the ratio of sodium ions to chloride ions is 1Na : 1Cl. Therefore, a sodium chloride molecule is composed of 50% sodium and 50% chloride.

H2co3
What is the empirical formula of a compound that contains 75 percent Ag and 25 percent Cl by mass?
AgCl
Explain why the percent composition of certain compounds are not sufficient to determine the compounds molecular formulas?
Because unlike the empirical formula, the molecular formula does not have to be the simplest ratio.If by chance you are given the percent composition of the elements in a substance, you could calculate the empirical formula and then the empirical formula's mass. However, the molecular formula equation is molecular formula= (empirical formula)n, where n is the mass of the molecular formula divided by the mass of the empirical formula. You would, therefore, need to know the mass belonging to the molecular formula, which you are not given.

What is the importance of percentage composition?
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.

How do you know when to solve for a empirical formula?
If it tells you to find the empirical formula when percent composition is given or if the mass of each element is given in a specific compound.
