number of molecules / avogadro's number * molecule molecular = mass
explanation:
we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –
6.022
x
10
23
. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,
u
f
6
will have a gram-molecular weight of 352g.
it would be a gas formation
the formula for the conversion of temperature from degree celsius to kelvin is:
the sample of water at is converted to kelvin temperature by using the above formula as:
on comparing the two samples of water at or we can say that at
and at
respectively. the difference between the temperatures of two samples of water is:
hence, one can say that the sample of water at is greater than the sample of water at
by
