Answer:
Water vapor pressure is a function of temperature (and pressure as well). It increases with the temperature. When vapor is produced on the heat surface, bubble forms. The size of the bubble is determined by the buoyancy and the water pressure at the location.
Answer:
Molality of solution=10.11 m
Explanation:
We are given that
Given mass of KCl(WB)=75.3 g
Given mass of water (WA)=100 g=100/1000=0.1 kg
1 kg=1000 g
Molar mass of H=1.01 g
Molar mass of K=39g
Molar mass of Cl=35.45 g
We have to find the molality of a solution.
Molar mass of KCl(MB)=39+35.45
Molar mass of KCl(MB) =74.45 g
Number of moles of solute (KCl)=
Number of moles of solute (KCl)=
Number of moles of solute (KCl)=1.011 moles
Molality of solution
=
Using the formula
Molality of solution=
Molality of solution=10.11 m
13.48 is your answer.
M=moles/liters we have M=.115 and moles=1.55
Input those values into the equation
.115=1.55/L
Solve for L
1.55/.115=13.48
