Question
If you have a Bradford reagent that you have to dilute 1:4. After dilution the final volume should be 20ml, how much of the Bradford reagent would you use to make this final volume (diluted solution)?
Solution
To prepare a 1:4 dilution with a final volume of 20 ml, you would need to use 1 part of the Bradford reagent for every 4 parts of diluent.
Here are the steps to calculate the volume of Bradford reagent needed:
-
First, add the parts of the Bradford reagent and the diluent together. In this case, 1 part Bradford reagent + 4 parts diluent = 5 parts total.
-
Next, divide the final volume by the total number of parts to find the volume of each part. In this case, 20 ml ÷ 5 parts = 4 ml/part.
-
Finally, multiply the volume of each part by the number of parts of the Bradford reagent to find the volume of Bradford reagent needed. In this case, 4 ml/part × 1 part Bradford reagent = 4 ml of Bradford reagent.
So, you would need to use 4 ml of the Bradford reagent to make a 20 ml 1:4 dilution.
