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. Stock Calculate Final Concentration needed ml added 20% NaCl 1.5% ? 30% K2HPO4 2% ? 2.5 M NH4 Cl 0.1M ? 10 mg/ml ampicillin water 0.05 mg/ml ? water To 300 ml ?
You have a 20% stock of NaCl, a 30% stock of K2HPO4, 2.5 M NH4Cl and 10 mg/ml stock of ampicillin.
