A 13.0 kg iron weightlifting plate has a volume of 1650 cm3 . What is the density of the iron plate in g/cm3?
Salsk061 [2.6K]
11.0 kg = (11.0 kg)(1000 g/kg) = 11000 g
(11000 g)/(1400 cm3) = 7.857 g/cm3
Simplified = 7.86 g/cm3

How long would it take to produce enough aluminum to make a case (24 cans) of aluminum soft drink cans if each can used 3 g of a
kozerog [31]

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.

\text{Moles of Al}=\frac{\text{Mass of Al}}{\text{Molar mass of Al}}

Molar mass of Al = 27 g/mol

\text{Moles of Al}=\frac{72g}{27g/mol}=2.67mol

As, 1 mole of Al has 3 Faradays

So, 2.67 mole of Al has = 2.67\times 3=80.1 Faradays

and,

Charge = 80.1\text{ Faradays}\times \frac{96500\text{ coulombs}}{1\text{ Faradays}}=7.73\times 10^6\text{ coulombs}

Current = 5.00\times 10^4A\times \frac{93.9}{100}=46950A

Now we have to calculate the time.

Time=\frac{Charge}{Current}=\frac{7.73\times 10^6}{46950}=164.6s\aaprox 165s

Hence, it takes time to produce 3 g of aluminium is, 165 seconds.
