Question- A 6.00 % (m/v) NaCl solution contains 35.1g of NaCl. What is the total volume (V) of the solution in milliliters?
Articulate your respond with the appropriate units.
For lab we formed an initial equilibrium system by adding 10mL of water, 1 drop of 1M Fe(NO3)3 as well as 1 drop of 1M KSCN. After that perturbed the equilibrium by adding another drop of 1M Fe(NO3)3. Explain how to write the balanced net ionic eq..
