I am Guessing Sperm and egg
Answer:
You will need 10 mL of stock Tris, 15mL of stock NaCl and enough water to bring the total volume to 500 mL.
Explanation:
<u>The desired buffer contains:</u>
- Total volume of 500 mL
- Tris 30mM
- NaCl 150mM
<u>The stock solutions are:</u>
- 1.5M = 1500mM Tris
- 5M = 5000mM NaCl
We can use the formula C1V1=C2V2 to calculate the volume of each stock required to prepare the buffer.
<h2>
<u>Tris</u></h2>
- C1= 1500 mM
- V1=?
- C2= 30mM
- V2= 500 mL
1500 mM x V1 = 30mM x 500 mL
V1 = (30mM x 500 mL) / 1500 mM
V1 = 10 mL
<h2>
<u>NaCl</u></h2>
- C1= 5000 mM
- V1=?
- C2= 150 mM
- v2= 500 mL
5000 mM x V1 = 150mM x 500 mL
V1 = (150 mM x 500 mL) / 5000 mM
V1 = 15 mL
You will need 10 mL of stock Tris, 15mL of stock NaCl and enough water to bring the total volume to 500 mL.
