Answer : It takes time to produce 3 g of aluminium is, 165 seconds.
Explanation :
As we are given that the mass of aluminium is, 3 grams. Now we have to calculate the total mass of aluminum.
Total mass of aluminum = 3g × 24 = 72 g
Now we have to calculate the moles of aluminum.
Molar mass of Al = 27 g/mol
As, 1 mole of Al has 3 Faradays
So, 2.67 mole of Al has = Faradays
and,
Charge =
Current =
Now we have to calculate the time.
Hence, it takes time to produce 3 g of aluminium is, 165 seconds.
The density of carbon tetrachloride, given the data is 1.59 g/mL
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
with the above formula, we can determine the density of carbon tetrachloride. Details below:
<h3>How to determine the density of carbon tetrachloride</h3>
The following data were obtained from the question:
- Mass of flask = 345.8 g
- Mass of flask + carbon tetrachloride = 703.55 g
- Mass of carbon tetrachlorcide = 703.55 - 345.8 = 357.75 g
- Volume of carbon tetrachlorcide = 225 mL
- Density of carbon tetrachlorcide =?
Density = mass / volume
Density of carbon tetrachlorcide = 357.75 / 225
Density of carbon tetrachlorcide = 1.59 g/mL
