At what temperature would a 1.15 m NaCl solution freeze, given that the van't Hoff factor for NaCl is 1.9? Kf for water is 1.86
MariettaO [177]

Answer:

-4.1°C

Explanation:

The freezing-point depression (ΔTf) is a colligative property that can be calculated using the following expression:

ΔTf = i × Kf × m

where,

i: van't Hoff factor

Kf: freezing-point depression constant

m: molality

ΔTf = 1.9 × 1.86°C/m × 1.15 m = 4.1 °C

The freezing-point of pure water is 0°C. The freezing-point of this solution is:

0°C - 4.1°C = -4.1°C

PV = nRT. If P = 1 atm, V = 5.0 liter, R = 0.0821 L.atm/mol.K, and T = 293 K; what is the value of n?
Leya [2.2K]

Answer:

n = 0.207 mole

Explanation:

We have,

P = 1 atm

V = 5 liter

R = 0.0821 L.atm/mol.K

T = 293 K

We need to find the value of n. The relation is as follows :

PV = nRT

Solving for n,

n=\dfrac{PV}{RT}\\\\n=\dfrac{1\times 5}{0.0821 \times 293}\\\\n=0.207\ \text{mol}

So, the value of n is 0.207 mol.

How do you draw the structure of methylcyclohexane?
Mekhanik [1.2K]

<u>Methylcyclohexane:</u>

The chemical formula of the organic compound, methylcyclohexane is \mathrm{CH}_{3} \mathrm{C}_{6} \mathrm{H}_{11}. It is branched into the group of saturated hydrocarbon.

Note: Refer the attached image for the structure of methylcyclohexane

<u>Structure of methylcyclohexane:</u>

  • It is a monosubstituted cyclohexane because it has one branching through the attachment of single methyl group on one carbon of the cyclohexane ring.
  • Being very toxic to the aquatic ecosystem, the methyl group of this compond in its axial position experiences a steric strain or steric crowding.
