6. Calculate the stoichiometric formula of a compound, which is defined by the mass composition: C: 63.144390874821 % H: 5.29971240648 % N: 21.659512652847 % O: 9.896384065853 % A(C) 12,01; A,(H) = 1,008; A,(N) = 14.0067; A (0) - 15,9994 Add the appropriate coefficients to particular elements

Complete combustion of a 0.500 g sample of a pure hydrocarbon yielded 0.973 g CO 2 and 0.319 g H 2O. The empirical formula of this hydrocarbon is

What are the steps broken down and calculations to calculate percentage yield, theoretical yield and actual yield in a chemical equation?

The concept of determining which reactant is limiting and which is in excess is akin to determining the number of sandwiches that can be made from a set number of ingredients Assuming that a cheese sandwich consists of 2 slices of bread and 3 slices of cheese, determine the number of whole cheese sandwiches that can be prepared from 52 slices of bread and 87 slices of cheese sandwiches Which of the two ingredients limits the number of sandwiches that can be made? slices of bread slices of cheese What quantity of the ingredient in excess remains? slices

A newly discovered metalloprotein, which contains four atoms of Fe per molecule of protein, is found to be 0.747% Fe by mass. Calculate the molar mass of the metalloprotein

ABS plastic is a polymer consisting of three monomer units: acrylonitrile (C₃H₃N), butadiene (C₄H₆), and styrene (C₈H₈). A sample of ABS plastic contains 13.7% N by mass. It took 1.56 g of Br₂ to react completely with a 2.00 g sample of ABS plastic. Bromine reacts 1:1 (by moles) with the butadiene units in the polymer and nothing else, so bromination is a method for determining the quantity of butadiene in the polymer. What is the percent by mass of styrene in the polymer?

Upon combustion, a 0.8009 gg sample of a compound containing only carbon, hydrogen, and oxygen produces 1.6004 gg CO2CO2 and 0.6551 gg H2OH2O. Find the empirical formula of the compound.
