Question

Liquid benzene (C6H6) flows through a pipe with a mass flow rate of 71.0 g/s. Given that the density of benzene is 0.8765 g/cm3, find:

a.) The molar flow rate in mol/min:

b.) The volumetric flow rate in L/hr:

Answer #1

How much heat is required to convert 22.8 g of liquid benzene
(C6H6) at 58 ∘C to gaseous benzene at 100 ∘C? The boiling point of
benzene is 80.1 ∘C and Cm [C6H6(l)] = 136.0 J/(mol⋅∘C), and ΔHvap =
30.72 kJ/mol, Cm [C6H6(g)] = 82.4 J/(mol⋅∘C).

A liquid (ρ = 1.65 g/cm3) flows through a horizontal pipe of
varying cross section as in the figure below. In the first section,
the cross-sectional area is 10.0 cm2, the flow speed is 246 cm/s,
and the pressure is 1.20 105 Pa. In the second section, the
cross-sectional area is 4.50 cm2. (a) Calculate the smaller
section's flow speed. m/s (b) Calculate the smaller section's
pressure. Pa

When 8.05 g of an unknown compound X was dissolved in 100 g of
benzene C6H6, the vapor pressure of the
benzene decreased from 100 torr to 94.8 torr at 26 degrees C. (MW
C6H6 =78.0 g/mol.)
a.) What is the mole fraction for unknown compound X?
b.) What is the molar mass of unkown compound X?

Toluene (C7H8, molar mass = 92.13 g/mol)
an organic compound often used as a solvent in paints is mixed with
a similar organic compound benzene (C6H6,
molar mass 78.11 g/mol). Calculate the molarity, molality,
mass percent, and mole fraction of toluene in 2.00 x
103 mL of solution that contains 75.8 g of toluene and
95.6 g of benzene. The density of solution is 0.857
g/cm3.

A stream of hot dry nitrogen flows through a solvent recovery
unit that contains liquid benzene. A substantial portion of the
benzene vaporizes in the unit and is carried off by the nitrogen.
The combined gases leave the unit at 150°C and 1.2 bar and enter a
condenser in which a portion of the benzene is condensed. The
remaining gas leaves the condenser at 20°C and 30 bar. The partial
pressure of benzene in the feed to the condenser is...

1.What is the volumetric flow rate of a solution with density 1.5
kg/m3 flowing at a velocity of 5 m/s and a mass flow rate of 500
g/min? What is the area of the pipe? If it is circular, what is the
radius?
2.Suppose that a river with a molar flow rate of 10000 mol/s
meets another, larger river flowing at 500000 m3/s at room
temperature. What is the mass flow rate of the river downstream of

At a particular temperature, the partial molar volume of liquid
A (MM = 69.5 g mol-1) is 55.1 cm3 mol-1 and that of liquid B (MM =
127.2 g mol-1) is 87.1 cm3 mol-1. Given that the mole fraction of
liquid A is 0.37, find the mass in kg of 23.8 L of the
solution.

Water flows through a 5-cm-diameter pipe at the
average velocity of 1.25 m/s.
(a) In the dimensions of L/s, what is the volumetric
flow rate?
(b) If the diameter of the pipe is reduced by 20% at a
constriction, by what percentage does the water’s velocity
change?
