Answer:
6.85g/mol
Explanation:
According to the Graham's law of diffusion,the rate of diffusion is inversely proportional to the square root of molecular mass.
k=r√m.m
k=constant
r=rate of diffusion or effusion
m.m=molecular mass
taking ''1'' and '2" to be the two gases 1=oxygen,2=unknown gas
r1√m1=r2√m2,molar mass of oxygen=16
mathematically√m2=229√16/350
√m2=2.617
m2=6.85g/mol
Answer: 5 protons 6 neutrons and 5 electrons. and atomic number is 5.
Hope this helps!
Answer:
The temperature of the solute/solvent without any external effect would decrease.
Explanation:
As the bonding between the solute particles is really strong, therefore a large amount of energy is required to overcome these forces. So that the new bonding between the solute and solvent is created.
In order to achieve this, there will be a lot of energy required and that is through the heating process. So the solution will require energy so the solute will dissolve fully either by provision of external force i.e stirring or by heating.
