Part D: Determining the chemical formula from empirical data: A chemical formula is a simple whole-number ratio of the atoms, ions, and molecules that comprise a substance. Unfortunately, the values you will calculate of the moles for each component will be decimals and not simple whole numbers-but you can still use those values to find the ratio! Consider this example, where I have just determined the moles of each of 3 components: x = 0.003535 y = 0.002667 z = 0.01434 The easiest method of obtaining a whole number ratio is to first divide each value by the smallest of the three (in this case, divide each by 0.002667) and compare the new values. x = 1.324 y = 1 z = 5.377 Now if you compare the values after the decimal, you might notice that 0.324 and 0.377 are close to 0.333 which is 1/3. If all values are multiplied by 3, that may bring the values closer to whole numbers: 1/3 $2.Al(s) x = 3.976 ? 4 8.976-74 y = 3 z = 16.13 ??? 16 ->> Those are now fairly close to whole numbers, and we may feel safe assuming the ratio of x:y:z is close to 4:3:16. Do a similar analysis with your mole ratios of Cu, SO4, and H?O to determine believable formulas for the compound and write them in the form of Cux(SO4)y ZH?O in
