divide a fraction that both numbers can divide same number
example
500 divide 10 is 50
------
1000 divide 10 is 100
50
----=50%

To determine the empirical formula from percent by mass, first convert the percentages to grams. Then divide the grams of each element by its molar mass to find the moles. Next, divide the moles of each element by the smallest number of moles to get the simplest ratio. Finally, use this ratio to write the empirical formula.
To determine the chemical formula from percent composition, you need to convert the percent composition of each element into moles. Then, divide the moles of each element by the smallest number of moles to find the ratio of elements. Finally, use this ratio to write the chemical formula.
The most simplified ratio of the elements in the substance is approximately C3H7N. This is determined by dividing the percent composition of each element by its molar mass and finding the simplest whole number ratio.
To write a percent as a decimal, divide it by 100 To write a percent as a fraction, put it over 100 To reduce a fraction to its simplest form, find the GCF of the numerator and the denominator and divide them both by it. If the GCF is 1, the fraction is in its simplest form. 75% = 0.75 = 75/100 = 3/4
30 percent means 30 out of each 100. In this case it will be written as30 = 3100 10
any percent as a fraction is put over 100 so: 45 __ 100 now find the fraction in simplest form so take out 5 from each number 9_ 20
2 percent
