How many L are there in 450 mL?
[tex]450 mL=[?] L[/tex]
Give your answer in standard form. (L)
[$\square$]
Answer (2)
To convert 450 mL to liters, divide by 1000 to get 0.45 L. In standard form, this is expressed as 4.5 × 1 0 − 1 L. Thus, 450 mL equals 4.5 × 1 0 − 1 L.
;
Convert 450 mL to liters by dividing by 1000: 450 mL = 1000 450 L = 0.45 L .
Express 0.45 in standard form as 4.5 × 1 0 − 1 .
Therefore, 450 mL = 4.5 × 1 0 − 1 L .
The final answer is 4.5 × 1 0 − 1 .
Explanation
Understanding the Problem We are given a volume of 450 mL and asked to convert it to liters (L), expressing the answer in standard form.
Conversion Factor We know that 1 L = 1000 mL. To convert mL to L, we divide the number of mL by 1000.
Calculating Liters So, 450 mL = 1000 450 L = 0.45 L .
Standard Form To express 0.45 in standard form, we write it as a × 1 0 b , where 1 ≤ a < 10 and b is an integer. In this case, 0.45 = 4.5 × 1 0 − 1 .
Final Answer Therefore, 450 mL is equal to 4.5 × 1 0 − 1 L.
Examples
Imagine you are baking and a recipe calls for 450 mL of milk, but your measuring cups are in liters. Converting 450 mL to liters helps you accurately measure the milk needed for your recipe. This conversion is also useful in other real-life scenarios, such as measuring liquids in cooking, science experiments, or when dealing with different units of volume in international contexts. Understanding unit conversions allows for accurate measurements and consistent results in various practical applications.
