Answer:
The answer to your question is π = 12.47 atm
Explanation:
Data
mass of Magnesium citrate = 25.5 g
volume of solution = 244 ml
temperature = 37°C
molar mass C₆H₆MgO₇ = (12 x 6) + (1 x 6) + (24 x 1) + (16 x 7) = 214 g
Osmotic pressure = π = ?
Process
1.- Calculate the moles of magnesium citrate
214 grams ----------------- 1 mol
25.5 grams --------------- x
x = (25.5 x 1)/214
x = 0.119
2.- Calculate molarity
Molarity = moles/volume
Molarity = 0.119/0.244
Molarity = 0.49
3.- Calculate osmotic pressure
π = MRT
π = (0.49)(0.0821)(37 + 273)
π = (0.49)(0.0821)(310)
π = 12.47 atm
Explanation:
I haven't studied this in quite a long time but I will try my best to answer your question.
Gravity is a force that pulls things towards it and everything has gravity. The larger an object the stronger it's force of gravity and the more it pulls objects towards it. In our solar system the Sun is the largest object (by far) and therefore has the highest gravity. This means that the planets orbit the sun since the gravity of the sun is pulling the planets towards it. This stops planets from flying to outer space.
The thing that stops the planets from crashing into the sun is that they are travelling too fast. The planets are trying to travel in a straight direction, but the gravity and their speed in another direction kind of counteract and create a "medium" I guess you could call it, meaning the planet just orbits the sun.
Answer: W + BgCz2 arrow WCz + Bg
2 W + BgCz2 arrow 2 WCz + Bg
Explanation:
Cz has 2 so you balcne the other side of WCz.
Since you Balcanes the Cz you changed the W and you Balcanes the other W on the left side.
Answer:
the left one
Explanation:
heavier means it goes faster
Fossils can not be formed in igneous rock because before it cooled from the liquid magma state, any renants of fossils would be destroyed and melted... they form in sedimentary because thats where they can be buried and perserved the easiest, metamorphic would destroy them from the pressures and temperatures involved in there formations
