Question

(3) (b) The mean concentration of red blood cells in an adult is 5.5 × 106 cells per mm3 1 mm3 = 0.000001 dm3 Calculate the mean number of red blood cells in 1 dm3 Give your answer in standard form.

Answer 1

The correct answer is - 5.5*10^12 cells per dm^3

Step-by-step explanation:

Given:

The mean concentration of red blood cells in an adult = 5.5 × 10^6

or = 5500 000

1 mm3 = 0.000001 dm^3

Solution:

Then, 1 dm^3 = 1000000 mm^3

(55000000 × 1000000) = 5500,000,000,000

= 5.5 × 10^12
