What is the empirical formula of a compound which is 64.80 percent carbon 6.35 percent hydrogen and 28.83 percent sulfur?
C4h2s
36 is what percent of 150?
The formula for finding the percent is =The given number/Total number *100 Here the given number is 36 . The total number is 150 . Therefore Percent = 36/150*100=24%
How do you convert degrees into slope in Excel?
To convert 'D' degrees into a percent slope, you could use the Excel formula:= 100 * TAN ( D / 57.296 )
What is the formula for changing a numbers into a percentage?
To find x as a percentage of y: percent = 100x/y. Eg 17 as a percentage of 68 = 1700/68 = 25.
The percent of change found when the original amount decreases is called the percent of?

Can you determine the molecular formula of a substance from its percent composition?
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.

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.
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.
