Question

A coworker gives you a bottle of sodium phosphate buffer they made that has a concentration of 174 mM. The procedure you're currently doing in lab requires a concentration of 25 mM. You need a total of 1.45 L of the diluted buffer for your procedure. Calculate the amount of the stock solution you need AND the amount of H2O you should add to dilute it for the final volume you need. Show work (write and scan/submit, or explain in words) for full credit.

Step 1

Given: - Concentration of stock solution (sodium phosphate buffer) = 174 mM - Concentration needed for the procedure = 25 mM - Volume needed for the procedure = 1.45 L Using the dilution equation: \[ C_1V_1 = C_2V_2 \] Where: - \( C_1 \) = concentration of stock Show more…
