An unknown compound containing tellurium and bromine is analyzed and it is determined that 28.53% of the compound by mass is composed of tellurium. How many moles of Te are present in 100.00 g of the compound?
Homework Answers
mass of Te in the compound = 28.53 % of 100g = 28.53 g
number of moles of Te = mass of Te / atomic mass of Te
number of moles of Te = (28.53 g / 127.6 g/mol) = 0.224 mol
