- A compound contains 4.56g. of Pb, 2.3g Cl, and 3.1g 0. What is the percent composition for each element?
please show work

Add up all the grams to get 9.96, then divide the amount if each element by the total;
4.56 of Pb divided by 9.96 = 0.4578313 now multiply by 100 and get 45.8% of Pb, then do the same for the rest of the elements, hope this helped <3

They are like other investigations? say there was a murder u have to do blood test and finger prints which run through a lab. 

Hope the image of the frequency formula
