compound acidifier p002 formula calculator

Calculate the empirical formula of citric acid . Express

Now the values above are not exact, but close enough to the ratio of the molecular formula of citric acid. To obtain the formula you want all whole numbers, because 3.65 is roughly 3.5 you can multiply all the values by 2 (so that 3.5 becomes a whole number; 7) to yield: 3x2 = 6 C 4x2 = 8 H and 3.5x2 = 7 O C6H8O7 is your answer.
