Answer:
0.4mol
Explanation:
number of moles(n)=mass/molar mass of glucose(M)
n=75g/180.156M
n=0.4mol
Dynamo theory makes certain predictions. One is that a dynamo-induced magnetic field can exist only where a molten core exists within a fast-spinning planet. Small celestial bodies, such as Mars and the asteroids, long ago lost their heat, which shuts down the necessary convection near their cores. Venus is large enough to have retained its heat, but it spins very slowly, reducing the motion of its core and weakening the field. Mercury, which is too small to retain its primordial heat, does have a magnetic field as a result of its extreme inclination, which is allowed for in dynamo theory.
Explanation:
On one side , there is high concentration of potassium ion and chloride ions. And on other sides high concentration of sodium ions and phosphate ions.
![[K^+][Cl^-]|[Na^+][PO_2^{-}]](https://tex.z-dn.net/?f=%5BK%5E%2B%5D%5BCl%5E-%5D%7C%5BNa%5E%2B%5D%5BPO_2%5E%7B-%7D%5D)
Cell is permeable only to chloride ions.As we can see that chloride ions are only present on the outside of cell .
As we know solute particles move from higher concentration to lower concentration side that is to equalize the concentration of solute particles on both sides. So, chloride ion will move inside the cell until the concentration of chloride ions become equal on both the sides which will result in swelling up of cell.
The amount of a
substance can be converted into grams of that substance by using the molar
mass. It is a physical property of a substance which describes the mass per
mole of the substance. The molar mass of CH3OH is 32.04 g/ mol. Multiplying the
given amount of CH3OH with the molar mass will yield to the mass of the substance.
<span>9.09x10^24 molecules CH3OH ( 1 mol / 6.022x10^23 molecules) (32.04 g/mol) = 483.63 g CH3OH
Dividing the molar mass of N2O which is 44.08 g/mol to the given amount will yield to the number of moles.
0.183 g N2O / 44.08 g/ mol =0.0042 mol N2O</span>
