MolarityMolality 1. The number of moles of solute present in per liter of solution.1. The number of moles of solute present in 1kg of solvent. 2. It depends on volume.2. It depends on mass. 3. Volume changes with temperature, hence it is temperature dependent.3. It depends on mass which is independent of temperature. To convert Molality value into Molarity value, we have to use the following formula:- m=1000×(d−M)×Mb1000×M or, M=(m×Mb)+1d where, M: molarity, m: molality, d: density, Mb: Molecular mass.

Inductive effect in simple terms is the result of permanet dipole produced due to polarity of the sigma bond developed due to difference in electronegativity.
This causes a permanent state of bond polarization, where the more electronegative atom has a slight negative charge ({tex}\delta{/tex}-) and the other atom has a slight positive charge ({tex}\delta{/tex}+)

The energy released by fusion is three to four times greater than the energy released by fission, giving the "hydrogen" bomb, or H-bomb, more power. The name comes from the fact that it uses a fusion of tritium and deuterium, hydrogen isotopes.

Ziya Rehaman 3 years, 2 months ago

(K-273)/100=C/100=(F-32)/180 So, (K-273)/100=25/100=(F-32)/180 => K= 298 => F= 77

Gaurav Seth 3 years, 4 months ago

The normal room temperature which would be comfortable for living is around 20 - 25° C.

In chemistry, The upper limit 25°C is taken as Standard room temperature .

We know that,
Temperature on Celsius + 273 = Temperature on Kelvin.

Now,
25°C = 25 + 273 = 298K .

Therefore, The standard room temperature in Kelvin is 298 k

Isotonic Solution:

If the medium surrounding the cell is of exactly the same water concentration as inside the cell, there will be no net movement of water across membrane resulting in no change in size of cell. Such solution is called Isotonic solution.

(iii) Hypertonic solution:

If the medium surrounding the cell has a lower water concentration than inside the cell, i.e., if the solution is highly concentrated, then the cell will lose water through osmosis. Such concentrated solution is called Hypertonic solution.
