Chemistry Word Problem Please Help

While you are doing heavy work, your heart pumps up to 25.0 L of blood per minute. Your brain gets about 3-4% by volume of your blood under these conditions. What volume of blood in liters is pumped through your brain in 125 minutes of work that causes your heart to pump 22.0 L per minute, 3.43% of which goes to your brain?

Solution

Hello Maria, I hope I can help you!

Here is the math worked out for the problem:

22.0L of blood per minute * 125 minutes = 2750.0L blood * .0343 = 94.3L blood to brain

Always make sure to keep track of your units 🙂
