first try to find the percentage of carbon from CO2 and hydrogen from h20 and sulphur from so2 then calculae percentage of oxygen from it. now find mole of each element from its percentage .then find its atomic ratio.this would give the value o empirical formula. thank you very much!

where we could use the mass of carbon, mass of hydrogen, and mass of oxygen to parse out the percentage composition of each element in glucose. When we dissolve solids in water, we can use the chemical formula and the mass of
How to find the empirical formula from a given composition of compounds All the elements needed in finding an empirical compound Finding the percent composition of an empirical compound What the empirical compound shows The contrasts with a chemical formula Skills Practiced This wo...
Step 1: Find The Mass (Amount) Of Each Element In The Compound We start the procedure by finding the exact amount (in grams) of each element that makes up the compound being studied. Let’s assume that the compound whose empirical formula is to be found is XaYbZc. Chemical analysis of...
The empirical rule is applied to anticipate probable outcomes in a normal distribution. For instance, a statistician could use it to estimate the percentage of cases that fall in each standard deviation. Consider that the standard deviation is 3.1 and the mean equals 10. In this case, the firs...
How to find standard deviation with mean and probability? How do you calculate the area within one standard deviation of a mean? Explain using an example. In a distribution for which the mean is 25 and the standard deviation is 5. What percentage of all scores occur at 30 o...
The primary difference is that an empirical probability requires that probability experiment. One has to toss the coin X times to find out how many times heads or tails will come up. Classical probability is used without an experiment or where it isn't possible to perform an experiment and th...
There exist empirical formulas which allow us to use the past performance of the software system to provide a reasonably good prediction of this future number. In this paper, we provide a theoretical justification for these empirical formulas. 展开 ...
We simulated over 200 cities worldwide to investigate how the street network affects vehicle routes. We demonstrate that there is a ubiquitous super-linear relationship between time and distance when optimal route are chosen. More precisely, the average
