What is the initial volume, in ml needed to prepare 150 ml of 3.0% (m/v) glucose from 22% (m/v) glucose

we all know that V1S1=V2S2

Explanation:

Now V2=150ml

         S2=3%

          S1=22%

           V1=?

                    V1S1=V2S2

                     V1=V2S2/S1

                     V1=  150*3/22

                          =   20.45ml

The initial volume needed to prepare 150ml 3%glucose from 22%glucose is 20.45ml.

possibly, yes.

explanation:

the amount of sugar you take in is dangerously high, risk of heart disease, high risk of diabetes, and etc.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
