Answer:
b 0.027 atm
Explanation:
It is possible to solve this question using Raoult's law that says that the partial pressure of each component of an ideal mixture of liquids is equal to the vapour pressure of the pure component multiplied by its mole fraction in the mixture.
To know mole fraction of water you need to know how many moles of water have 1L. Moles are:
1L × (1000g/1L) × (1mol/18,01g) = <em><u>55,5 moles of water</u></em>.
Mole fraction is:
55,5 moles of water / (55,5+5) total moles = <em><u>0,917</u></em>
Thus, vapour pressure of the solution is:
0,917 × 0,03atm = <em>0,027atm</em>
Right answer is:
<em>b 0.027 atm
</em>
