Answer : The moles of methane gas could be,
Solution :
According to the Graham's law, the rate of effusion of gas is inversely proportional to the square root of the molar mass of gas.
or,
where,
= rate of effusion of fluorine gas
= rate of effusion of methane gas
= moles of fluorine gas =
= moles of methane gas = ?
= time = 12.3 min (as per question)
= molar mass of fluorine gas = 38 g/mole
= molar mass of methane gas = 16 g/mole
Now put all the given values in the above formula 1, we get:
Therefore, the moles of methane gas could be,
Answer:
The pressure is 4.939 atm
Explanation:
As we know
PV = nRT
where P is the pressure
V is the volume
n is the total number of moles
R is the gas constant
and T is the temperature
Substituting the given values we get -
The pressure is 4.939 atm
Answer:
Explanation:
Hello there!
In this case, according to the given chemical reaction, it is possible to realize there is a 1:2 mole ratio of sulfuric acid to water; thus, given the mass of the former and its molar mass (98.07 g/mol), it is possible to determine the mass of produced water as shown below:
