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 : $\chi_1, \chi_2 \& \chi_3$

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

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

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

Deposition of sediment will most likely form a

Ierofanga [76]

I would say delta reason: Sediments are deposited throughout the length of the stream as bars or floodplain deposits. At the mouth of the stream, the sediments are usually deposited in alluvial fans or deltas, which represent a lower‐energy, more “permanent” depositional environment that is less susceptible to changes in the stream
