if you want to prepare 5% w/v, then weigh 5gram of DMSO and dissolve into water to make final volume 100mL. You can vary the quantity as per your requirement.

5% w/v is 5 gram in 100 ml solution.

Density of DMSO is 1.1 gram/ml, 5 gramm are approximately 4.545 ml.

So you will dissolve 4.545 ml DMSO in 95.55 ml water.

To prepare 100 μm of 5% DMSO solution, take 5 μm of DMSO, highest purity grade (>99.99%), and add to it 95 μm distilled water.

Dear researcher

You can dissolve 4.5 ml of DMSO in 95.5 ml of distilled water.

5 grams of DMSO in 95 ml of water ====

25 grams of DMSO in 475 ml of water.
