Once you enter this formula it returns the hours in numbers and minutes (if you have) in decimals. How this formula work s. As I said before, Excel stores date and time in numbers and when you deduct end time from the start time it returns a decimal. And when further you multiply it by 24 (total number of hours in a day) it converts that decimals into the number of hours and minutes. 3. Get Different in.

When percentages are given, always consider 100.0 g sample. 2-Determine the number of moles of atoms of each element by using the molar mass of the element, M x, (n x = m x /M x). 3-Obtain the smallest whole number ratio of the atoms (the empirical formula) by dividing each number of moles of atoms by the smallest number obtained. 4-If necessary, multiply all resulting numbers by the smallest.

A chemical formula identifies each constituent element by its chemical symbol, and indicates the proportionate number of atoms of each element. In empirical formulas, these proportions begin with a key element and then assign numbers of atoms of the other elements in the compound—as ratios to the key element.For molecular compounds, these ratio numbers can always be expressed as whole.
