A compound, KBrOx, where x is unknown, is analyzed and found to contain 52.92% Br. What is the value of x?
Step-by-step solution Step 1 of 3 To calculate the formula weight of the given compound that is KBrOx We have to know the definition of formula weight The formula weight is the sum of the atomic weights of everything that's in that particular formula. In the case of H2, the formula weight of H 2is the sum of the weights of two hydrogens and one oxygen. Formula weight of potassium =39.09 amu. Formula weight of bromine =79.9 amu Formula weight of oxygen =16.0amu KBrOx=1*(39.09amu)+1(79.9amu)+x(16.0amu) =118.99 amu+16xamu.
