SUMMARY

To prepare a 500 ml lab stock of 20% (w/v) SDS, you need to calculate the weight of SDS required. A 20% (w/v) solution means 20 grams of SDS per 100 ml of solution. Therefore, for 500 ml, you will need 100 grams of SDS. This calculation is based on the definition of weight/volume percentage, which is crucial for accurate preparation of chemical solutions.

PREREQUISITES
  • Understanding of weight/volume percentage (w/v) calculations
  • Familiarity with laboratory measurement techniques
  • Knowledge of SDS (Sodium Dodecyl Sulfate) properties
  • Basic skills in preparing chemical solutions
NEXT STEPS
  • Research the properties and applications of Sodium Dodecyl Sulfate (SDS)
  • Learn about preparing different concentrations of solutions in a laboratory setting
  • Study the implications of using weight/volume versus volume/volume concentrations
  • Explore safety protocols for handling SDS in the laboratory
USEFUL FOR

Chemistry students, laboratory technicians, and researchers involved in biochemical experiments requiring SDS solutions.

Homework Statement



How would you prepare a 500 ml lab stock of 20% (w/v) SDS

That is all that is stated in the problem.

Homework Equations



I'm assuming for w/v the volume would be 0.5L but the weight I'm not sure.


The Attempt at a Solution



0.5L x .20 = .1g SDS / .5 L .. is that correct? doesn't make sense to me.

Please help!
