We know,
1000 cm³ = 1 L
1 cm³ = 1 / 1000 L
508 cm³ = (1 / 1000) * 508 L =
0.5080 L
So, 508 cm³ = 0.5080 LNow,
We know,
22.4 L = 1 mole
1 L = 1 / 22.4 mole
0.5080 L = (1 / 22.4) * 0.5080L =
0.0227 moles
So, 0.0277 moles moles of are added to the tank before it is used for paintball.
Answer:
1 × 10⁸ He atoms
Explanation:
Step 1: Given data
- Diameter of a helium atom (d): 1 × 10² pm
- Total distance to be covered (D): 1 cm
Step 2: Convert "d" to meters
We will use the conversion factor 1 m = 10¹² pm.
1 × 10² pm × (1 m / 10¹² pm) = 1 × 10⁻¹⁰ m
Step 3: Convert "D" to meters
We will use the conversion factor 1 m = 100 cm.
1 cm × (1 m / 100 cm) = 0.01 m
Step 4: Calculate the number of atoms of He required
We will use the following expression.
D/d = 0.01 m / 1 × 10⁻¹⁰ m = 1 × 10⁸
