Question

Assuming that each human being has 60 trillion body cells (6 x 10¹3) and that the earth's

population is 6 billion (6 x 10°), calculate the total number of living human body cells on
this planet. Is this number smaller or larger than a mole? Divide the larger value by the
smaller to determine the relative size of the two values.

Answer 1

The total number of living human body cells on Earth is approximately 5.98 x 10^16 times larger than a mole.

Step-by-step explanation:

To calculate the total number of living human body cells on this planet, we need to multiply the number of body cells in one human being by the total population of the Earth. Using the given data, we have: 60 trillion cells x 6 billion people = 360 sextillion cells. This number is larger than a mole, which is approximately 6.022 x 10^23, as a mole represents the number of particles in a substance. To determine the relative size of the two values, we divide the larger value (360 sextillion) by the smaller value (6.022 x 10^23), giving us approximately 5.98 x 10^16. Therefore, the total number of living human body cells on this planet is about 5.98 x 10^16 times larger than a mole.
