Explanation:
Here, we want to calculate the final volume
We use the general gas equation here:
P1 is the initial pressure which is 0.850 atm
V1 is the initial volume which is 4.25 L
T1 is the initial temperature which is (23 + 273.15 = 296.15 K)
P2 is the final pressure which is 1.50 atm
V2 is the final volume which is unknown
T2 is the final temperature (11.5 + 273.15 = 284.65 K)
Substituting the values, we have:
The mass of ore required is 21 700 t.
r = 750 cm
V =
= 
= 1.767 × 10⁹ cm³
The density of lead is 11.34 g/cm³.
So mass of lead sphere = 1.767 × 10⁹ cm³ ×
= 2.004 ×10¹⁰ g
2.004 ×10¹⁰ g ×
= 2.004 × 10⁷ kg
2.004 × 10⁷ kg ×
= 2.004 × 10⁴ t
92.5% efficiency means 92.5 t Pb per 100 t of ore.
Mass of ore = 2.004 × 10⁴ t Pb ×
= 2.17 × 10⁴ t ore = 21 700 t ore
r = 750 cm
V =
The density of lead is 11.34 g/cm³.
So mass of lead sphere = 1.767 × 10⁹ cm³ ×
2.004 ×10¹⁰ g ×
2.004 × 10⁷ kg ×
92.5% efficiency means 92.5 t Pb per 100 t of ore.
Mass of ore = 2.004 × 10⁴ t Pb ×
