Now scientists from the University of Sussex have found a new way to know more about dark matter. It is often referred to as dark which has nothing to do with the colour of any substance but to do with the unknown nature of cosmic entities known as dark matter and dark energy. If the initial amount p leads to a percent change x and the second percent change is y then the final amount is p 1 001 x1 001 y.
For instance if you had a 800 g sample of a compound that was 200 g element X and 600 g element y then the percent composition of each element would be.
For instance if you had a 800 g sample of a compound that was 200 g element X and 600 g element y then the percent composition of each element would be. Percent calculations are fundamental to many classes especially science courses. Percent concentration does not refer to this quantity. Heres a step-by-step tutorial on how to calculate percent.
