Answer: The molality of solution is 0.66 mole/kg
Explanation:
Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.
where,
n = moles of solute
= weight of solvent in g
moles of 
= 
Now put all the given values in the formula of molality, we get
Therefore, the molality of solution is 0.66 mole/kg
Answer:
Explanation:
= Initial pressure = 200 kPa
= Final pressure
= Initial temperature = 
= Final temperature = 
We have the relation
The pressure that would be exerted after the temperature change is .
I have the same question right now and i think that it is D
Answer:
6.022×1023
Here, it has been asked how many eggs are in one mole of eggs. The eggs represent the unit which can be atom, ion or molecule. So by the definition of mole, 6.022×1023number of eggs are present in one mole of eggs.
