Question 20

There are 500 milliliters in 0.5 liters.

0.5 liters is equivalent to 500 milliliters, as 1 liter is equal to 1,000 milliliters. Therefore, to convert 0.5 liters to milliliters, you multiply 0.5 by 1,000.

A) 5,000

This option is incorrect because 5,000 milliliters represents 5 liters, not 0.5 liters. The conversion from liters to milliliters requires multiplying by 1,000, which does not yield this amount for 0.5 liters.

B) 5

This option is also incorrect as 5 milliliters is a fraction of a liter, specifically 0.005 liters. This value does not accurately correspond to 0.5 liters when converted to milliliters.

C) 500

This option is correct because 0.5 liters is exactly 500 milliliters. The conversion factor of 1 liter being equal to 1,000 milliliters confirms that multiplying 0.5 by 1,000 results in 500.

D) 50

This option is incorrect since 50 milliliters is only one-twentieth of a liter. This value does not correctly represent the conversion of 0.5 liters to milliliters.

Conclusion

The correct answer is 500 milliliters, as it accurately reflects the conversion of 0.5 liters based on the standard metric relationship where 1 liter equals 1,000 milliliters. All other options fail to represent this conversion accurately, demonstrating a misunderstanding of metric units.
