A chemist prepares a solution of iron(11) bromide (FeBry) by measuring out 62. mg of FeBr, into a 250. mL volumetric flask and filling to the mark with distilled water.
Calculate the molarity of Br" anions in the chemist's solution.
Be sure your answer is rounded to 2 significant digits.

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
