Determine how many gmol, kmol, and lbmols there are in 50 kilograms of n-hexane.
Artist 52 [7]

Answer: 581 gmol

0.581 kmol

1.28\times 10^{-3}lbmol

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{50\times 1000g}{86g/mol}=581mol

1. The conversion for mol to gmol

1 mol = 1 gmol

581 mol= \frac{1}{1}\times 581=581gmol

2. The conversion for mol to kmol

1 mol = 0.001 kmol

581 mol= \frac{0.001}{1}\times 581=0.581kmol

3. The conversion for mol to lbmol

1 mol = 2.2\times 10^{-3}lbmol

581 mol= \frac{2.2\times 10^{-3}}{1}\times 581=1.28\times 10^{-3}lbmol

The heat of vaporization of carbon tetrachloride (CCl4) is 197.8 J/g. How much energy is absorbed by 1.35 mol CCl4 when it vapor
const2013 [10]

Energy absorbed from changing the phase of a substance from the liquid phase to gas phase can be calculated by using the specific latent heat of vaporization. Calculation are as follows:

 

<span> Energy = 1.35 mol  CCl4 ( 153.81 g / 1 mol ) x 197.8 J/g </span>

 

<span>Energy = 41071.88 J</span>
