Use the equation below to solve the following problem.   Calculate the number of grams of BaCl2 in 250 mL of a 0.300 M solution. To receive full credit:  You must use the math equation editor in the tool bar to, if necessary, show the calculation of the molar mass and to insert the final equation (with numbers and units) that you used to solve the problem.  Be sure to include the answer. Or, solve the problem on your own paper and upload the picture into the Unit 3 Exam pictures dropbox immediately after submitting the exam.
