cannot be cut into smaller pieces
Answer:
Incomplete question. You didn't give the volume of HNO3
Solution :
We know that :
and 
Then, 
..................(1)
Where,
= amount of solvent (in kg)
= amount of solute (in kg)
= molar mass of solute (g/mole)
= molality of solution (mole/kg)
Given :
= 
, 
= 0.250 kg, = 24.3 g
Then putting this values in the equation is (1),
g/mole
So, the molar mass of the unknown compound is 158.49 g/mole.
Answer:
The transiontions metal group
Explanation:
Answer:
Vaporization
Explanation:
Vaporization is the change of a specie to the gaseous state. To 'disappear' in this case simply means to change to the gaseous state.
Substances with high vapour pressure tend to be easily converted to vapour phase. Hence if Glade air freshener gel 'disappears' easily, then it has a high vapour pressure and is easily converted to vapour (gas).
