Answer:

Atoms are the building blocks of cells, which are the building blocks of all things. Every thing that exists is comprised of cells of various elements and compounds, held together by atomic bonds.

assuming that each human being has 60 trillion body cells in that the earths population is 6 billion calculate the total number

sesenic [268]

3.6 x 10²³

Explanation:

Given parameters:

Number of cell per body = 60 trillion body cells

Population of the earth = 6 billion

Unknown:

Total number of living human body cells = ?

Solution:

To solve this problem, simply find the product:

Total number of living human body cells = number of cell per body x population of the earth

1 trillion = 1 x 10¹²

60 trillion = 6 x 10¹³

1 billion = 1 x 10⁹

6 billion = 6 x 10⁹

Total number of living human body cells = 6 x 10¹³ x 6 x 10⁹

= 6 x 6 x 10⁽¹³⁺⁹⁾

= 36 x 10²² or 3.6 x 10²³

Air is a mixture of gases that is about 78.0% n2 by volume. when air is at standard pressure and 25.0 ∘c, the n2 component will

ArbitrLikvidat [17]

Step first:

Since, 78.0 percent $N_{2}$ by volume is present in the air which implies there are 78 moles of $N_{2}$ present in 100 moles of air.

Now,

Mole fraction of $N_{2}$ = $\frac{Moles of N_{2}}{Total moles of gases in the mixture}$

Mole fraction = $\frac{78}{100} mol$

= 0.78

Partial pressure is equal to the multiplication of total pressure and mole fraction.

Partial pressure = $0.78\times 1 atm$ (as 1 atm is atmospheric pressure)

= 0.78 atm.

Step second:

Henry's law constant is calculated by:

$S_{g}=k\times P_{g}$

where,

$S_{g}$ is solubility of gas

$P_{g}$ is partial pressure of gas

$k$ is henry's law constant

Substitute the value of solubility and partial pressure to find the value of Henry's law constant in above formula:

$4.88\times 10^{-4} M=k\times 0.78 atm$

k = $\frac{4.88\times 10^{-4}M}{0.78 atm}$

= $6.25\times 10^{-4} M atm^{-1}$

Thus, Henry's Law constant is $6.25\times 10^{-4} mol L^{-1} atm^{-1}$ .
