Show all calculations.
Initial amount of triphenylmethanol in moles: 0.208 g / 260.3 g/mol = 0.00079 mol
Initial mass of 33% HBr solution = 0.6 mL HBr solution x 1.354 g/mL = 0.81 g
Initial mass of HBr = 0.81 g x .33 = 0.27 g HBr
Initial amount of HBr (in mol) = 0.27 g / 80.91 g/mol = 0.0033 mol
Final amount triphenyl bromide in mol = 0.077 g / 323.23 g/mol = 0.00024 mol

You are performing an experiment in a lab to attempt a new method of producing pure elements from compounds. the only problem is that you do not know what element will form. by your previous calculations you know that you will have 6.3 moles of product. when it is complete, you weigh it and determine you have 604.4 grams. what element have you produced?
