The mass number of aluminium hydroxide is 78 thus, the number of moles in 0.745 g is:
no. of moles= mass/ RFM
= 0.745/78
=0.00955moles
Therefore the 0.00955 moles should be in the 35.18 ml
therefore 1000ml of the solution will have:
(0.00955ml×1000ml)/35.18
=0.2715moles
The solution will be 0.27M hydrochloric acid
Answer:
A great example would be a fish, it needs the water to breathe just like how we humans need oxygen. If a fish were to get out of the water it would die.
Explanation:
Answer:
636 mm Hg
Explanation:
The pressure in the gas container is equal to the atmospheric pressure minus the height of mercury:
Atmospheric pressure = 722 torr = 722 mm Hg
Height = 8.60 cm = 86 mm Hg
Pressure = 722 - 86 = 636 mm Hg
So none of the given options is correct, the correct answer is 636 mm Hg.
My best guess would be gases because the state of gas is highly compressible
