Mol of Kr gas = 1.244
<h3>Further explanation</h3>
In general, the gas equation can be written
<h3> PV=nRT
</h3>
where
P = pressure, atm
V = volume, liter
n = number of moles
R = gas constant = 0.08205 L.atm / mol K
T = temperature, Kelvin
P=1.31 atm
V=23.3 L
T=26+273=299 K
mol of sample :
Answer:
Explanation:
Hola,
Dado que la molaridad de una solución es definida en términos de las moles de soluto y el volumen de la solución en litros:
Primero debemos calcular las moles de hidróxido de sodio, teniendo en cuenta que su masa molar es de 40 g/mol:
Luego, el volumen el litros:
Así, calculamos la concentración molar de la solución:
Saludos!
Carbon monoxide poisoning has certain symptoms in order to detect its presence but development of mees lines on the figer and toe nails does not include on its symptoms. Mees lines appears if the person experience poisoning of thallium, arsenic or other heavy metals. Mees lines also appear if the person is experiencing or suffering from renal failure.
Answer:
H2 > N2 > Ar > CO2
Explanation:
Graham's law explains why some gases efuse faster than others. This is due to the difference i their molar mass. Generally; The rate of effusion of gaseous substances is inversely proportional to the square rot of its molar mass.
This means gases with low molar masses would have higher efusion rate compared to gases with higher molar masses.
So now we just need to compare the molar masses of the various gases;
Ar - 39.95
CO2 - 44.01
H2 - 2
N2 - 28.01
To obtain the order in increasing rate, we have to order the gases in decreasing molar mass. This order of increasing rate is given as;
H2 > N2 > Ar > CO2
