Depending upon the tip of the of a dropper pipet, there are approximately 20 drops per milliliter of water. the experimental procedure, parts a and b indicates the addition of 5-10 drops of each solution to the test tube. calculate the volume range in milliliters for a solution.

Answer : Volume range in milliliters for a solution is 0.25 ml to 0.5 ml.

Solution : Given,   1 ml = 20 drops

There are 20 drops present in     =    1 ml of water

                 In 1 drop                       =    

        And in 5 drops                     =    

                                                      =     0.25 ml

For range calculation, 0.25 ml is multiplied by the 2, we get

    = 0.25 × 2

    = 0.5 ml

Hence, the volume range is 0.25 ml to 0.5 ml.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
