A chemist prepares a solution of calcium bromide CaBr2 by measuring out 307.g of calcium bromide into a 500.mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in /molL of the chemist's calcium bromide solution. Round your answer to 3 significant digits.

58750.08068 is the answer i think

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

it is b that is the answer.
