Two hundred kg of liquid contains 30% butane, 40% pentane, and the rest hexane (mass %) Determine: The mole fraction composition

OlgaM077 [116]

Answer:

The mole fraction composition of the liquid is :

Mole fraction of butane, pentane and hexane are 0.3638,0.3908 and 0.2454 respectively.

Explanation:

Mass of the liquid mixture = 200 g

Percentage of butane = 30%

Mass of butane = $\frac{30}{100}\times 200 g=60 g$

Moles of butane = $n_1=\frac{60 g}{58 g/mol}=1.0345 mol$

Percentage of pentane= 40%

Mass of pentane= $\frac{40}{100}\times 200 g=80 g$

Moles of pentane= $n_2=\frac{80 g}{58 g/mol}=1.1111 mol$

Percentage of hexane = 100% - 30% - 40% = 30%

Mass of hexane = $\frac{30}{100}\times 200 g=60 g$

Moles of hexane = $n_2=\frac{60 g}{86 g/mol}=0.6977 mol$

Mole fraction of butane, pentane and hexane : $\chi_1, \chi_2 \& \chi_3$

$\chi_1=\frac{n_1}{n_1+n_2+n_3}=\frac{1.0345 mol}{1.0345 mol+1.1111 mol+0.6977 mol}=0.3638$

$\chi_2=\frac{n_2}{n_1+n_2+n_3}=\frac{1.1111 mol}{1.0345 mol+1.1111 mol+0.6977 mol}=0.3908$

$\chi_3=\frac{n_1}{n_1+n_2+n_3}=\frac{0.6977 mol}{1.0345 mol+1.1111 mol+0.6977 mol}=0.2454$

What the oxidation state of sulfur in sulfite?

RUDIKE [14]

Answer:

Explanation:

$SO^{-2} _{3}$ , Oxygen always works with -2. You multiply with the number of atoms -2*3= -6

S=x+(-6)=-2

x-6=-2 -> x= -2+6 -> x= +4

What is the mass of a sample of iron if that sample lost 2300J of heat energy when it cooled from 80 oC to 30°C? The specific he

irakobra [83]

102 grams.
Equation:
Quantify of heat = mass x specific heat x difference in temperature
We have: quantity of heat : 2300J
specific heat: .449 J/g
difference in t: 80 - 30 = 50
Solve for mass: 2300 = mass x 0.449 x 50
mass = 102.449
2 sig-figs --> 102 grams

Who described the atom as being like plum pudding?

matrenka [14]

Answer:

Explanation:

J.J. Thomson

The plum pudding model is an early 20th century model of an atom. It was later found to be wrong. It was proposed by J.J. Thomson in 1904, after the electron had been discovered, but before the atomic nucleus was discovered.
