Given in question ;
volume of ideal gas (v1) = 1.62 L
pressure on ideal gas (p1) = 1atm
volume of sample (v2) = to find
pressure of sample (p2) = 85 atm
As the Temperature is constant. Thus, we apply the Boyle's Law ; P₁V₁ = P₂V₂
To find V₂.
P₁V₁ = P₂V₂
(1 atm)(1.62 L) = (85 atm)(V₂)
V₂ = 1.62/85
V₂ = 0.019 L
Thus the volume of sample in ocean is 0.019 L.
What is Boyle's Law ?
Boyle’s law is a gas law which states that the pressure exerted by a gas (of a given mass, kept at a constant temperature) is inversely proportional to the volume occupied by it. In other words, the pressure and volume of a gas are inversely proportional to each other as long as the temperature and the quantity of gas are kept constant. Boyle’s law was put forward by the Anglo-Irish chemist Robert Boyle in the year 1662.

Answer:
The charge of cobalt in the salt is + 2.
Explanation:
The charge of the salt = 0 . This is because it is neutral.
Charge of cobalt = ?
Charge of oxygen = -2 (This is a constant value, it is -2 only in peroxides)
Charge of salt = Charge of cobalt + Charge of oxygen
0 = x + (-2)
x = + 2
The charge of cobalt in the salt is + 2.
Answer: Partial pressure of helium gas is 162.24 atm.
Explanation:
