According to Boyle's Law,
" the volume of a fixed mass of gas is inversely proportional to the pressure applied on it'.
Mathmatically,
V ∞ 1 / P
Or,
V = k / P
Explanation:
The balloon filled with Neon gas outside the chamber will have greater volume than in the chamber because the pressure in the chamber is high as compared to outside. So, the outside force brings the molecule of gas to get closer to each other.
(i) We start by calculating the mass of sugar in the solution:
mass of sugar = concentration × solution mass
mass of sugar = 2.5/100 × 500 = 12.5 g
Then now we can calculate the amount of water:
solution mass = mass of sugar + mass of water
mass of water = solution mass - mass of sugar
mass of water = 500 - 12.5 = 487.5 g
(ii) We use the following reasoning:
If 500 g solution contains 12.5 g sugar
Then X g solution contains 75 g sugar
X=(500×75)/12.5 = 3000 g solution
Now to get the amount of solution in liters we use density (we assume that is equal to 1):
Density = mass / volume
Volume = mass / density
Volume = 3000 / 1 = 3000 liters of sugar solution
Answer:
Not sure what the specific answer you want is but here's mine..
Earth science or geoscience includes all fields of natural science related to the planet Earth. SO.. They would study how the world works. AN example is natural disasters.
Explanation:
Hope this helps.
The answer is 1296.75 g
Molar mass of <span>Fe2(SO4)3 is the sum of atomic masses of its elements:
Mr(</span>Fe2(SO4)3) = 2Ar(Fe) + 3Ar(S) + 12Ar(O)
Ar(Fe) = 55.84 g/mol
Ar(S) = 32.06 g/mol
Ar(O) = 16 g/mol
Mr(Fe2(SO4)3) = 2 * 55.84 + 3 * 32.06 + 12 * 16
= 111.68 + 96.18 + 192
= 399.9 g/mol
Thus there are 399.9 g in 1 mol and x grams in 3.25 mol:
399 g : 1 mol = x : 3.25 mol
x = 399 g * 3.25 mol : 1 mol
x = 1296.75 g
They are pumped across the mitochondrial inner membrane against their concentration gradient (to where their concentration is high); as the H+ ions flow back to where their concentration is low, they drive ATP synthase to form ATP
