Non-electrolyte = A, 10.6 grams, dissolved in solvent B, 740 grams, the boiling point of the solution is higher than the boiling
Thepotemich [5.8K]

Answer:

2.1 °C/m

Explanation:

Hello, for this exercise, consider the formula:

T_{solution}-T{solvent}=K_bm_solute

Considering that the difference in the temperature is 0.284°C, and the given molality by:

m_{solute}=\frac{10.6g\frac{1mol}{106g}}{740g*\frac{1kg}{1000g} } \\m_{solute}=0.135m

Now, solving for K_b, we get:

K_b=\frac{0.284C}{0.135m}\\K_b=2.1 C/m

Best regards.

20 PTS!!! What is the volume of a gas at 90.0°C, if it occupies 1.41 L at 170°C?
Margarita [4]

Answer:

1.72 L

Explanation:

Initial Temperature of the gas T =90°+273= 363 K

Initial Volume of the gas V1= 1.41 L

Final temperature of the gas T2= 170°c +273= 443 K

Final volume of the gas V2= ????

Using Charles law;

V1/T1 = V2/T2

V1T2= V2T1

V2= V1T2/T1

V2= 1.41×443/363

V2= 1.72 L
