Question

mework-Solution Stoichiometry ese problems are similar to what you have done in lab, but not identical. If you need more formation, refer to your General Chemistry textbook for assistance receive fuill credit, you must SHOW ALL YOUR WORK!I Name 1. if 16.97 g of NaBr is dissolved in enough water to make 160.ml of solution, what is the molar concentration of NaBri b. How many militers of 0.10 M NaBr would you need to supply 6.31 g of NaBr? 2. For each of the following preparations, tell how many grams of solute would be necessary for its preparation, a. 0.90 L of 0.15 M BaCl, b. 50 ml of 0.018M KMnO 3. What would be the molar concentrations of the solute in each of the following solutions? a. 0.50 L containing 38.6 g of NaCIO b. 0.25 L containing 41.5 g of CHO 4. If you require 500. ml of 0.25 M NaOH, how many milliliters of 1.39 M NaOH must you dilute? 123

Explanation / Answer

I'll answer the first question only if you want the answers to the other questions, you attach them to a new question for each.

1)

M=g/p.f.*V

M=16.97/102,894*0.16

M=1.03 mol/L
