Ethanol has a Kb of 1.22 Degrees C/m and usually boils at 78.4 Degrees Celcius. How many mol of an nonionizing solute would need
Gala2k [10]

Answer:

0.3097 moles of an nonionizing solute would need to be added.

Explanation:

Molal elevation constant = k_b=1.22^oC/m

Normal boiling point of ethanol = T_o=78.4^oC

Boiling of solution =T_b=86.30^oC

Moles of nonionizing solute = n

Mass of ethanol (solvent) = 47.84 g

Elevation boiling point:

\Delta T_b=T_b-T_o

\Delta T_b=86.30^oC-78.4^oC=7.9^oC

\Delta T_b=K_b\times  m

m=\frac{\text{Moloes of solute}}{\text{Mass of solvent(kg)}}

7.9^oC=1.22^oC/m\times \frac{n}{0.04784 kg}

n = 0.3097 mol

0.3097 moles of an nonionizing solute would need to be added.

What is the molarity of a HCl solution that contains 8.53 g of HCl in 372 mL of solution?
kirill [66]
First you find moles of HCl.

8.53gHCl(1 mol HCl/36.46gHCl)=0.234mol HCl

Then since molar it is mol/L you divide the number on moles of HCl by the amount of solution in L (0.372L).
Good luck!
