1 atm = 760 mm Hg
Where 760 mm is the height of Mercury for 1 atm.
For 0.900 atm,
Height of mercury = 0.900*760 = 684 mm Hg
B. Aquaculture means "cultivating small acreages of land."
Explanation:
Aquaculture is the growing of fishes, crustaceans, molluscs, oysters and other marine organisms like algae in a small acreage of farm. Normally, the carryign capacity per acreage would be lower in the natural habitat – like in the oceans- but this is raised substantially in aquaculture due to adopting certain farming techniques. An example is by cycling the wastewater from teh fish tanks to plants that take up the waste as nutrients and oxygenate the water, The water is then recycled back to the tanks as cleaner water reusable by the fishes and teh cycle continues. This cycle ensures the sustainability of the farm even with very little water compared to the natural environment.
Answer:
Protein
Explanation:
Cholesterol is actually part lipid, part protein
Answer:
V = 20.97 L
Explanation:
Given data:
Mass of nitrogen = 23.4 g
Pressure of gas = 750 mmHg (750/760 = 0.99 atm)
Temperature of gas = 28°C (28+273= 301K)
Volume of gas = ?
Solution:
First of all we will calculate the number of moles of gas.
Number of moles = mass / molar mass
Number of moles = 23.4 g/ 28 g/mol
Number of moles = 0.84 mol
Now we will calculate the volume:
PV = nRT
V = nRT/P
R = general gas constant = 0.0821 atm.L/mol.K
V = 0.84 mol× 0.0821 atm.L/mol.K× 301 K / 0.99 atm
V = 20.76 L/0.99
V = 20.97 L
