Physical trait is the major limitation present in the current classification system.
Explanation:
- Classification is the process through which we see the relationship between various things.
- During classification we categorize things that helps us to make a proper subjective judgement.
- The limitation of classifications are they are biased , that is who are participating may not have same physical traits.
- As a result difference occurs in perceived value. Another huge problem is human beings make classification for satisfying their own purpose .
- The natural world behaves in its own way that is by not following any classification.
Assume 100 g of compound. This turns percent to mass. Calculate moles:
S ---> 30/32 = 0.9375
F ---> 70 / 19 = 3.6842
get whole number ratio:
0.9375 / 0.9375 = 1
3.6842 / 0.9375 = 3.93 = 4
Answer : SF4
Answer:
m = 7.29 grams
Explanation:
Given that,
Initial temperature, T₁ = 25ºC
Final temperature, T₂ = 31.5ºC
The specific heat of the metal is 0.89 J/gºC.
We know that the heat released due to the change in temperature is given by :
So, the mass of the piece is equal to 7.29 grams.
Answer:
volume = 13097674418.528dm³
Explanation:
n = (3.52)*10^32/(6.02)*10^23)
n = (584717607.97)
n = volume /molar volume
molar volume at stp = 22.4dm³
volume= 584717607.97 x 22.4
volume = 13097674418.528dm³
Answer : The correct option is, kilogram of solvent.
Explanation :
Molality : It is defined as the number of moles of solute present in one kilogram of solvent.
Or, we can say that the number of moles of solute per kilogram of solvent.
The unit of molality is mole per kilogram or mole/Kg.
The formula will be :
Hence, the molality is a unit of concentration that measures the moles of solute per kilogram of solvent.
