Suppose the Gas is acting ideally, Then, According to Ideal Gas Equation;
P₁ V₁ = P₂ V₂ ----- (1)
Data Given:
P₁ = 885 torr
V₁ = 125 cm³
P₂ = 225 torr
V₂ = ?
Puting values in eq, 1;
V₂ = P₁ V₁ / P₂
V₂ = (885 torr × 125 cm³) ÷ 225 torr
V₂ = 491.66 cm³
Answer:
25000 ppm
Explanation:
<em>Parts Per Million </em>is defined as the number of parts of a solute per one million parts of a solution.
ppm = (Weight of Solute / Weight of Solution) × 10⁶ ---(1)
Let us suppose that the air (solution) weights 100 grams, then 2.5 % of water vapors will have following mass,
Mass of Vapors g / 100 g × 100 = 2.5
Or,
Mass of Vapors = 2.5 × 100 / 100
Mass of Vapors = 2.5 g
Hence, mass of water vapors is 2.5 g.
Now, putting mass of water vapors and air in eq. 1,
ppm = (2.5 / 100) × 10⁶
ppm = 25000
Answer:
Explanation:
The two green substances are not the same. Most of their properties are different, except some are alike. Since not all of their properties are matching, they are not the same substance.
