Answer:
1. Volume of osmium = 0.044 mL
2. Volume of Hydrogen = 11123.47 mL
3. Osmium is 251390 times denser than hydrogen
Explanation:
From the question given above, the following data were obtained:
Density of osmium = 22.6 g/mL
Density of Hydrogen = 8.99×10¯⁵ g/mL
Mass of osmium = 1 g
Mass of Hydrogen = 1 g
1. Determination of the Volume of osmium.
Density of osmium = 22.6 g/mL
Mass of osmium = 1 g
Volume of osmium =?
Density = mass /volume
22.6 = 1 / volume
Cross multiply
22.6 × volume = 1
Divide both side by 22.6
Volume = 1 / 22.6
Volume of osmium = 0.044 mL
2. Determination of the Volume of Hydrogen.
Density of osmium = 8.99×10¯⁵ g/mL
Mass of osmium = 1 g
Volume of osmium =?
Density = mass /volume
8.99×10¯⁵ = 1 / volume
Cross multiply
8.99×10¯⁵ × volume = 1
Divide both side by 8.99×10¯⁵
Volume = 1 / 8.99×10¯⁵
Volume of Hydrogen = 11123.47 mL
3. Determination of the number of times osmium is denser than hydrogen.
Density of osmium (Dₒ) = 22.6 g/mL
Density of Hydrogen (Dₕ) = 8.99×10¯⁵ g/mL
Dₒ / Dₕ = 22.6 / 8.99×10¯⁵
Dₒ / Dₕ = 251390
Cross multiply
Dₒ = 251390 × Dₕ
Thus, osmium is 251390 times denser than hydrogen.
