compute volume and/ or weights of reagents to make the following solution.

Desired concentration: 22 ug/mL bovine serum albumin
Desired quantity: 100 mL
Given: 95% bovine serum albumin

I'm not sure how to do this so any help would be great. Thanks!

To calculate the volume and weights of reagents required to make a specific solution, we need to consider the desired concentration, volume, and the given concentration of the reagent.

Here are the steps to calculate the volume and weights of reagents for your specific solution:

Step 1: Convert the desired concentration from micrograms per milliliter (ug/mL) to milligrams per liter (mg/L).
- Desired concentration: 22 ug/mL
- Conversion factor: 1 mg/L = 1000 ug/mL
- Convert: 22 ug/mL * (1 mg/L / 1000 ug/mL) = 0.022 mg/L

Step 2: Determine the volume of the reagent needed.
- Desired quantity: 100 mL
- Volume = Desired quantity = 100 mL

Step 3: Calculate the weight of the given reagent.
- Given: 95% bovine serum albumin
- Given concentration = 95 g/100 mL
- Weight (g) = Given concentration * Volume (mL) = 95 g/100 mL * 100 mL = 95 g

Step 4: Calculate the weight of the reagent needed.
- Weight needed = Percent purity * Desired quantity * Desired concentration
- Percent purity = 95% (from the given reagent)
- Weight needed = 95% * 100 mL * 0.022 mg/L = 2.09 g

Therefore, to make a 100 mL solution with a desired concentration of 22 ug/mL bovine serum albumin, you will need to add approximately 2.09 grams of the 95% bovine serum albumin.
