Question

1. if you know that 1 liter is about the size of a water bottle and 1 milliliter equals about 1 drop from a medicine dropper, then estimate the volume of the liquid item pictured below.

a 2 liters
b 10 liters
c 30 milliliters
d 5 milliliters

1. estimate the volum item pictured belc best answer.

a 20 liters
b 200 liters
c 20 milliliters
d 2 milliliters

Explanation:

Step1: Recall the conversion between liters and milliliters

We know that \(1\) liter \( = 1000\) milliliters. A dropper is used for small - volume liquids.

Step2: Analyze each option for question 51

• Option A: \(2\) liters \(=2\times1000 = 2000\) milliliters. A dropper's volume is much less than \(2000\) milliliters.
• Option B: \(10\) liters \(=10\times1000=10000\) milliliters. This is way too large for a dropper.
• Option C: \(30\) milliliters. This is a reasonable estimate for the volume of liquid that a dropper can hold.
• Option D: \(5\) milliliters is too small for a typical dropper (a standard dropper usually holds more than a few milliliters).

Step3: Analyze each option for question 52

• Option A: \(20\) liters \(=20\times1000 = 20000\) milliliters. A perfume - like bottle (assuming a reasonable - sized bottle) is not \(20\) liters.
• Option B: \(200\) liters \(=200\times1000=200000\) milliliters. This is extremely large.
• Option C: \(20\) milliliters is too small for a bottle (a small bottle of liquid is usually more than \(20\) milliliters).
• Option D: \(200\) milliliters is a reasonable estimate for the volume of a bottle (similar to small cosmetic or perfume - like bottles).

Answer:

1. C. 30 milliliters
2. D. 200 milliliters
