The average adult has about 9.0 pints of blood. If 20 drops of blood is = to 1 mL. How many drops of blood does the average human contain?
Is the answer 85,1400 drops or 85,000 drops or neither? Thanks!
I figured 85,171.7 drops which would round to 8.5E4 to two significant figures (limited by the two in the 9.0). I went to Google and typed in 9 U.S. pints to mL and hit the enter button. Saved a lot of work.
To calculate the number of drops of blood in the average human, we first need to convert the volume of blood from pints to milliliters, and then convert milliliters to drops.
1 pint is equal to 473.176 milliliters. Therefore, the average adult has 9.0 pints x 473.176 milliliters/pint = 4,258.584 milliliters of blood.
Since 20 drops is equal to 1 milliliter, we can multiply the volume of blood in milliliters by 20 to find the number of drops.
4,258.584 milliliters x 20 drops/milliliter = 85,171.68 drops.
Therefore, the answer is neither 85,1400 drops nor 85,000 drops. The average human contains approximately 85,171.68 drops of blood.
Note: It's important to keep in mind that this calculation provides an estimate, as exact values may vary between individuals. Additionally, the average blood volume can vary based on factors such as age, gender, and overall health.
