The formula Upper E equals Upper W times Upper A is used to find the estimated blood volume of a patient with weight W, in kilograms, and average blood volume A, in milliliters per kilogram. Find the estimated blood volume of a toddler who weighs 9.7 kg and has an average blood volume of 75 mL/kg.

Estimated blood volume is  727.5 milliliters.

Step-by-step explanation:

We are given the following in the question:

where E is the estimated volume of the blood, W is the weight in kilograms and A is the average blood volume in in milliliters per kilogram.

We have to estimate blood volume of a toddler such that

W = 9.7 kg

A = 75 mL/kg

Putting the values, we get,

Thus, estimated blood volume is  727.5 milliliters.
