Ch. Ex. 50 - Determining the number of anion equivalents in Ringer's solution 1 attempt left Check my work Be sure to answer all parts. Ringer's solution is an intravenous solution used for replacement of electrolytes when an individual is dehydrated. Ringer's solution contains the following cations: Na (147 mEq/L), K´ (4 mEq/L), and Ca (4 mEq/L). (a) How many milliequivalents of Na are present in 175 mL of Ringer's solution? milliequivalents of Na (b)If the only anion in Ringer's solution is Cl , what is the concentration of Cl in mEq/L? mEq/L Na*

You have a 20% stock of NaCl, a 30% stock of K2HPO4, 2.5 M NH4Cl and 10 mg/ml stock of ampicillin. a. How many grams of NaCl would you need to weigh out to make up 150 ml of a solution?b. You will be preparing 300 ml of media. You need to dilute this 20% stock of NaCl, the 30% stock of K2HPO4, the 2.5 M NH4 how much stocks you need to add. Fill in the table below.

I had a 6.00 M NaOH solution and I diluted it to a 50mL solution of 0.300 M NaOh solution by adding 2.5 mL of NaOH and filled it up to the mark using DI water. I also had to make a 50mL of a 0.300 M NaCl solution by adding 0.8g of NaCl.  I then pipet 20mL of the 0.300M NaOH solution into a small beaker and pipet 10.0mL of 0.300 M NaCl into it. What is the molarity/concentration of NaOH in the new solution I created by dilution? I need to use the formula M1V1=M2V2
