Step-by-step explanation:
The question is:
The amount of red blood cells in a blood sample is equal to the total amount in the sample minus the amount of plasma. What is the total amount of blood drawn? Red blood cells = 45% Plasma = 5.5 ml
Solution:
We have given:
The amount of red blood cells in a blood sample is equal to the total amount in the sample minus the amount of plasma. We need to find how many ml is 1% of blood.
The equation we get is:
Red blood cells = total sample - amount of plasma
45% = 100% - 5.5 ml
Combine the percentages:
5.5 ml = 100%-45%
5.5 ml = 55%
0.1 ml = 1%
1% = 0.1 ml
Now you can find out red blood cells volume or total sample volume.
Red blood cells volume = 45% x 0.1ml/%
= 4.5ml
Total sample volume =100% x 0.1ml/%
= 10ml .
