The student appears to be asking about calculating blood volumes based on body weight in mL/kg. Conversions between liters and milliliters are directly calculated by multiplying by 1000. Understanding the composition and average volumes of blood in adults is key for accurate calculations.
The student's question seems to be about calculating blood volumes for different body weights given in milliliters per kilogram. To work with blood volume, it's important to understand that blood plasma is a significant component and that water makes up a large percentage of both plasma and total body weight. The values provided are most likely representing typical blood volume per kilogram for different categories of individuals or animals.
For the given examples (7. 2900 mL, 8. 1300 mL, etc.), the calculations could potentially be conversions from liters to milliliters or estimates of blood volume for individuals of various weights, considering the average adult body contains between 4.7 and 5.7 liters of blood. As each liter is equivalent to 1000 milliliters, conversions would simply involve multiplying the volume in liters by 1000 to get the volume in milliliters. For instance, a volume of 3 liters (Example 10) converts to 3000 milliliters.
