Final answer:
The question asks about converting milliliters to liters, which involves dividing the number of milliliters by 1000. A jug containing 200 milliliters of water is equivalent to 0.2 liters. This concept helps to understand volume measurement conversions in the metric system.
Step-by-step explanation:
The student has asked about the volume of water in a jug, requiring an understanding of metric units of capacity, specifically liters and milliliters. A liter (L) is a standard unit of volume in the metric system, used to measure the capacity of liquids like water. Since there are 1000 milliliters in a liter, converting milliliters to liters involves dividing the number of milliliters by 1000.
When converting from a smaller unit (milliliters) to a larger unit (liters), you divide the smaller unit by 1000. For example, to convert 200 milliliters to liters, you would use the equation 200 mL ÷ 1000 = 0.2 L. Thus, the jug contains 0.2 liters of water if it had 200 milliliters.
To further illustrate, if Jessica in the lab has 3.5 liters and needs to fill containers with 100 mL each, she would convert her 3.5 liters to milliliters by multiplying by 1000, yielding 3500 mL. She then divides this by the capacity of each container (100 mL) to find she needs 35 containers.
