Using a 10-ml graduate calibrated in 1-ml units, explain how you would measure 1.25 ml of a dye solution by the aliquot method. use water as the diluent. module 3: units of measurement 2 0

Take 5 ml of dye and add 3 ml of water

Thus,

The total volume of solution becomes = 8 mL

now,

This solution of 8 mL contains part of dye and part of water.

Next step is to take out 2 mL of solution

thus,

Volume of dye in 2 mL solution =

or

Volume of dye in 2 mL solution = 1.25 mL

hence,

the 1.25 mL dye is measured.

Step-by-step explanation:

Given:

10-mL graduate calibrated in 1-mL units

dye solution to be measured = 1.25 mL

Now,

take 5 ml of dye and add 3 ml of water

Thus,

The total volume of solution becomes = 8 mL

now,

This solution of 8 mL contains part of dye and part of water.

Next step is to take out 2 mL of solution

thus,

Volume of dye in 2 mL solution =

or

Volume of dye in 2 mL solution = 1.25 mL

hence,

the 1.25 mL dye is measured.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
