Question
How many liters of seawater would have to be processed to recover 1 kg of gold?
A cubic meter of ocean water has 6 x 10^-6 g gold. If the total mass of the water in Earth's oceans is 4 x 10^20kg, how many kilograms of gold are distributed throughout the oceans? Assume that the density of seawater is 1g/cm3. How many liters of seawater would have to be processed to recover 1 kg of gold. There's two questions to this problem. I would like to know how you would sove this problem and what's the answer?

Answer
To get kg of gold, first, you convert your density in g/cc to Kg/m^3 which is 1000 kg/m^3. But since total mass of the water in Earth's oceans is 4 x 10^20kg, you can get the the volume of the water in the oceans. 4 x 10^20kg/1000 kg/m^3 = 4 x 10^17 m^3. But one cubic meter of ocean water has 6 x 10^-6 g gold, so 4 x 10^17 m^3 x (6 x 10^-6 g gold/m^3) = 24 x 10^11 g of gold or converting to kilograms = 24 x 10^8 Kg. To get the number of liters, use 6 x 10^-6 g gold/ m^3 or convert to 6x10^-9 kg/m^3. and use the following conversion factors, 1 liter = 1000 cc or cm^3 m = 100 cm, m^3 = 10^6 cm^3, you should get 1.667 x 10^11(!!! ) Liters just to recover 1 kg of gold!!! So you see, nobody is applying to mine the oceans for gold.



Question
Using the PV=nRT law, how do I go from cm3 to a volume of liters so that I can use it in the equation?
We use liters to plug numbers into the equation, but what if you are given cm3 instead of liters? How do you convert. The problem reads: An 80.0cm3 sample of F gas at 0C, has a pressure of 765mmHg. If the gas is heated to 100C at 765mmHg, what is the final volume in cubic centimeters?

Answer
1 cm^3 = 1 mL. 1000 mL = 1 L. Standard conversion you should have memorized at the beginning of your chem class. :)



Question
What is the average colume of space, in liters that contains one H atom?
The average density of the universe as a whole is estimated to be about 1.5*10^-29 g/cm^3. If we assume that the entire mass is only hydrogen atoms, what is the average volume of space, in liters that contains one H atom? sorry, Volume*

Answer
1 H atom weight is 1/(6.02*10+23) or about 1.7x10-24 gram. Then 1.7*10-24 g/1.5*10-29 g/cm3 = 1.2 x 10+5 cm3 or abut 120 L.
