Uhmmm.. I am totally lost! Help?
There are 7.0 x 10^6 red blood cells in 1.0 mm^3 of blood. How many red blood cells are in 1 L of blood?
1 L = 1000 cc.
1000 cc x (10 mm/cm) x (10 mm/cm) x (10 mm/cm) = 1E6 mm^3
7.0E6 red blood cells/mm^3 x 1E6 mm^3 = ?
Sure, I can help you with that! To find out how many red blood cells are in 1 liter of blood, we need to convert the volume from mm^3 to L and then multiply it by the concentration of red blood cells.
Step 1: Convert mm^3 to L
To convert mm^3 to L, we need to divide the volume by 1,000,000 (since there are 1,000,000 mm^3 in 1 L). So, 1 mm^3 = 1/1,000,000 L.
Step 2: Multiply by the concentration
Now that we have the volume in liters, we can multiply it by the concentration of red blood cells. The concentration is given as 7.0 x 10^6 red blood cells per 1 mm^3.
Putting it all together:
1 mm^3 = 1/1,000,000 L (conversion factor)
Concentration = 7.0 x 10^6 red blood cells per 1 mm^3
Number of red blood cells in 1 L = (1/1,000,000 L) x (7.0 x 10^6 red blood cells/mm^3)
To solve this, you multiply 1/1,000,000 by 7.0 x 10^6. The result will give you the number of red blood cells in 1 L of blood.
To determine the number of red blood cells in 1 L of blood, follow these steps:
Step 1: Determine the volume of blood in 1 L.
- 1 L equals 1000 mL.
- The volume of blood is therefore 1000 mL.
Step 2: Convert the volume to mm^3.
- Since 1 mL is equal to 1 mm^3, the volume of 1000 mL is also equal to 1000 mm^3.
Step 3: Calculate the number of red blood cells in 1 L of blood.
- Given that there are 7.0 x 10^6 red blood cells in 1.0 mm^3 of blood, we can calculate the number of red blood cells in 1000 mm^3 using a proportion.
- Using the following proportion: (7.0 x 10^6 red blood cells / 1.0 mm^3) = (x / 1000 mm^3) where x is the number of red blood cells in 1000 mm^3.
- Cross-multiplying gives us: (7.0 x 10^6) x (1000) = 7.0 x 10^9 red blood cells.
Therefore, there are 7.0 x 10^9 red blood cells in 1 L of blood.
