Cost of rast apparatus used for determination of molecular weight of non-volatile solute
Answers
Atomic number of nitrogen:7
Nitrogen gas=2(N) (Nitrogen gas is diatomic)
Therefore:
electrons=7
Mass=14*2= 28
We also know that total number of electrons= total number of atoms X electrons per atom
No. of molecules=6.023*10^23 *moles
No. of moles=Normal mass/molecular mass=1.4/28=0.05 moles
Therefore no. of molecules=
Therefore number of atoms=2* no. of molecules=0.6*10^23
Therefore number of electrons =7* no. of atoms=7 * 0.6 * 10^23= 4.2 *10^23 electrons.
Answer:
Physics is one of the oldest academic disciplinesand, through its inclusion of astronomy, perhaps theoldest.[9] Over much of the past two millennia, physics, chemistry, biology, and certain branches of mathematics, were a part of natural philosophy, but during the Scientific Revolution in the 17th century these natural sciences emerged as unique research endeavors in their own right.[b]
