Answer:
4.8 g/mL is the density of chloroform vapor at 1.00 atm and 298 K.
Explanation:
By ideal gas equation:
Number of moles (n)
can be written as:
where, m = given mass
M = molar mass
where,
which is known as density of the gas
The relation becomes:
.....(1)
We are given:
M = molar mass of chloroform= 119.5 g/mol
R = Gas constant =
T = temperature of the gas =
P = pressure of the gas = 1.00 atm
Putting values in equation 1, we get:
4.8 g/mL is the density of chloroform vapor at 1.00 atm and 298 K.
Answer: The volume of product formed is 0.26 L
Explanation:
As is the the excess reagent,
is the limiting reagent as it limits the formation of product.
According to stoichiometry :
2 moles of give = 2 moles of
Thus 0.01 moles of will give =
of
According to ideal gas equation:
P = pressure of gas = 101.325 kPa = 1 atm
V = Volume of gas = ?
n = number of moles = 0.01
R = gas constant =
T =temperature =
Thus the volume of product formed is 0.26 L
Answer:
<h2>7.54 atm </h2>Explanation:
The required pressure can be found by using the formula for Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
From the question we have
We have the final answer as
<h3>7.54 atm </h3>Hope this helps you
