What is the density of CHCL3 vapor at 1.00atm and 298K?

Chemistry
1 answer:
Advocard [28]3 years ago
7 0

Answer:

4.8 g/mL is the density of chloroform vapor at 1.00 atm and 298 K.

Explanation:

By ideal gas equation:

PV=nRT

Number of moles (n)

can be written as: n=\frac{m}{M}

where, m = given mass

M = molar mass

PV=\frac{m}{M}RT\\\\PM=\frac{m}{V}RT

where,

\frac{m}{V}=d which is known as density of the gas

The relation becomes:

PM=dRT    .....(1)

We are given:

M = molar mass of chloroform= 119.5 g/mol

R = Gas constant = 0.0821\text{ L atm }mol^{-1}K^{-1}

T = temperature of the gas = 298K

P = pressure of the gas = 1.00 atm

Putting values in equation 1, we get:

1.00atm\times 119.5g/mol=d\times 0.0821\text{ L atm }mol^{-1}K^{-1}\times 298K\\\\d=4.88g/L

4.8 g/mL is the density of chloroform vapor at 1.00 atm and 298 K.

The boiling point of another member of this homologous series was found to be 309 k. What is the likely molecular formula for th
Sati [7]

Answer:

C5H12

Explanation:

In organic chemistry the boiling point of 309 k is of fifth member of alkane series which Pentane whose molecular mass is 72 g/mol.  Thus, we can say that the  molecular formula of the compound which has boiling point 309 K is C5H12.

What is the molarity of a solution of sulfuric acid if 49.0 mL of it are neutralized by a titration
vaieri [72.5K]

Answer:

THE MOLARITY OF THE ACID IS 0.232M

Explanation:

Molarity is the number of moles of solute per liter of a solution.

In titration, the molarity of the acid and the molarity of the base are related by this equation:

Ca VA / CbVb = na / nb

Ca = concentration of the acid = ?

Va = volume of the acid = 49 mL

Cb = concentration of the base = 0.333M

Vb = volume of the base = 68.4mL

Na = number of mole of acid = 1

Nb = number of mole of base = 2

Equation for the reaction:

H2SO4 + 2NaOH --------> Na2SO4 + 2H2O

Solving for the molarity of the acid, we have :

Ca = CbVbNa / VaNb

Ca = 0.333M * 68.4mL * 1 / 49mL *2

Ca = 22.7772 * 10^-3 / 98 *10^-3

Ca = 0.232M

The molarity of the acid is therefore 0.232M.

A cylindrical tube 13.5 cm high and 4.5 cm in diameter is used to collect blood samples. How many cubic decimeters (dm3) of bloo
Aleks [24]

Answer:

The cylindrical tube can hold 0.215 cubic decimeters of blood.

Explanation:

Diameter of the cylindrical tube = d = 4.5 cm

r = d/2 ,r = 2.25 cm

Height of the cylindrical tube = h = 13.5 cm

Volume of the cylinder = V = \pi r^2h

V=3.14\times (2.25 cm)^2\times 13.5 cm

V=214.6 cm^3=0.2146 dm^3\approx 0.215 dm^3

1 cm^3=0.001 dm^3

The cylindrical tube can hold 0.215 cubic decimeters of blood.
