Answer:The perimeter of the rectangle is \frac{47}{3} inch or 15.66 inch.

Explanation:

Length of strip (I) = 2\frac{1}{2} inch=\frac{5}{2}inch

Length of strip (II) = 5\frac{1}{3} inch=\frac{16}{3} inch

According to question two strips of length 1 inch and two strips of lenght \frac{5}{3} inch is used in making rectangle:

Perimeter of rectangle = Sum of all sides of rectangle

Perimeter of rectangle =\frac{5}{2} inch+\frac{5}{2} inch +\frac{16}{3} inch+\frac{16}{3} inch=\frac{47}{3} inch

The perimeter of the rectangle is \frac{47}{3} inch or 15.66 inch.

The partial pressure of O2 in air at sea level is 0.21atm. The solubility of O2 in water at 20∘C, with 1 atm O2 pressure is 1.38
adell [148]

Answer:

1.21x10^{-3} M

Explanation:

Henry's law relational the partial pressure and the concentration of a gas, which is its solubility. So, at the sea level, the total pressure of the air is 1 atm, and the partial pressure of O2 is 0.21 atm. So 21% of the air is O2.

Partial pressure = Henry's constant x molar concentration

0.21 = Hx1.38x10^{-3}

H = \frac{0.21}{1.38x10^{-3} }

H = 152.17 atm/M

For a pressure of 665 torr, knowing that 1 atm = 760 torr, so 665 tor = 0.875 atm, the ar concentration is the same, so 21% is O2, and the partial pressure of O2 must be:

P = 0.21*0.875 = 0.1837 atm

Then, the molar concentration [O2], will be:

P = Hx[O2]

0.1837 = 152.17x[O2]

[O2] = 0.1837/15.17

[O2] = 1.21x10^{-3} M
