Answer:
0.214 L
Explanation:
Step 1: Write the balanced equation
This is a single displacement reaction.
Zn(s) + 2 HCl(aq) ⇒ ZnCl₂(aq) + H₂(g)
Step 2: Calculate the moles corresponding to 0.625 g of Zn
The molar mass of Zn is 65.38 g/mol.
0.625 g × 1 mol/65.38 g = 9.56 × 10⁻³ mol
Step 3: Calculate the moles of H₂ produced from 9.56 × 10⁻³ moles of Zn
The molar ratio of Zn to H₂ is 1:1. The moles of H₂ produced are 1/1 × 9.56 × 10⁻³ mol = 9.56 × 10⁻³ mol.
Step 4: Calculate the volume occupied by 9.56 × 10⁻³ moles of hydrogen
Assuming standard pressure and temperature, 1 mole of hydrogen occupies 22.4 L.
9.56 × 10⁻³ mol × 22.4 L/1 mol = 0.214 L
Answer: Infusion time is 5.5 h
Explanation: Time is 470 ml / 85 ml/h = 5.5 h
Explanation:
Force applied on the gas will be as follows.
As, F = pressure × area. Hence, calculate the forces as follows.
= pressure × area
= 
= 
N
= pressure × area
= 
= 
N
- = 
N
Substituting the calculated values into the above formula as follows.
= (m + M) g
N = 
N = 
m = 472.76 kg
Thus, we can conclude that the mass is 472.76 kg.
