Question

A test tube used in science class has a volume capacity of 9 x 10^-3 liter. How many drops of a solution will it take to fill the test tube if each drop's volume is 3 x 10^-5 liter? Write these numbers in standard notation and then calculate the answer.

Answer 1

To fill a test tube with a capacity of 0.009 liters using drops each of 0.00003 liters, it would take 300 drops of the solution.

Step-by-step explanation:

The student has asked how many drops of a solution it would take to fill a test tube with a volume capacity of 9 x 10^-3 liters if each drop's volume is 3 x 10^-5 liters. First, we need to convert the scientific notation values into standard notation. The volume capacity of the test tube in standard notation is 0.009 liters, and the volume of each drop is 0.00003 liters.

To find out the number of drops needed to fill the test tube, we divide the total volume of the test tube by the volume of one drop: Number of drops = Test tube volume / Drop volume. Thus, Number of drops = 0.009 liters / 0.00003 liters = 300 drops. Therefore, it will take 300 drops of the solution to fill the test tube.
