The volume of a sample of water is 2.5 milliliters (ml). The volume of this sample in liters (l) is
(i) 2.5*10^-3 L, 2.5*10^-2 L, 2.5*10² L, 2.5*10³ L.

Solution:

Option (i) is the correct answer.

Liter is a basic metric unit which is used to measure the capacity of liquids and is equal to one cubic decimeter (1 liter = 1 dm³),

1,000 cubic centimeters (cm³), or 1/1,000 cubic meters (m³).

A liter is denoted with the letter 'l' or L.

Given that, the volume of a sample of water is 2.5 milliliters.

We know that 1 milliliter = 1/1000 liter

Therefore,

2.5 milliliters = 2.5 × 1/1000 = 2.5× 10^-3 liters

Note:

• To convert liters to milliliters, we multiply the given quantity by 1000.
• For example, if 5 liters has to be converted to milliliters.
• Then, 5 × 1000 = 5000 ml. Therefore, 5 liters = 5000 milliliters.
• 1 liter is equal to 1000 milliliters, 0.264 gallon, 1.0566 quarts, 2.1133 pint and 1 kilogram

The volume of a sample of water is 2.5 milliliters (ml). The volume of this sample in liters (l) is
(i) 2.5*10^-3 L, 2.5*10^-2 L, 2.5*10² L, 2.5*10³ L.

Summary:

For the given volume of a sample of water which is 2.5 milliliters (ml), the volume of this sample in liters (l) is 2.5× 10^-3 liters.
