Overview
I need answers to this two problems! This is for chemistry class.
PROBLEM 1! DIRECTIONS
Tell me what I have done wrong in solving this problem. There are several mistakes. Write out a correct solution to the problem.
I want to convert the concentration of a 5.67 % (m/v) solution to its equivalent concentration as %(m/m). The density of the solution has been measured to be 1.2 g/mL. My solution is
(5.67 % m/v) x 1.2 g/mL = 6.80 % (m/m).
PROBLEM 2
Solve the following problem showing all of your work and including all units. You can solve the problem in several steps or as a tandem conversion problem.
How many grams of Br2 are needed to completely convert 15.0 g Al to AlBr3 ?
Al (s) + Br2 (l) --> AlBr3 (hint: the equation is not balanced)
