Answer:
True
Explanation:
Specific volume is defined as volume occupied by unit mass. Its unit is meter cube/kg. Thus, specific volume can also be defined as volume occupied by 1 kg of mass.
It is also inverse of density as density is ratio of mass upon volume.
It is an intrinsic value as it does depend upon the amount of the substance.
Therefore, the given statement is true.
Answer:
220mL
Explanation:
The dilution formular was applied to obtain the volume of stock solution required to prepare the desired concentration of solution in the desired volume. Details are found in the image attached.
The standard ambient temperature and pressure are
Temperature =298 K
Pressure = 1atm
The density of gas is 1.5328 g/L
density = mass of gas per unit volume
the ideal gas equation is
PV = nRT
P = pressure = 1 atm
V = volume
n = moles
R= gas constant = 0.0821 Latm/mol K
T = 298 K
moles = mass / molar mass
so we can write
n/V = density / molar mass
Putting values
![Pressure=\frac{nRT}{V}=\frac{massXRT}{VXmolarmass}](https://tex.z-dn.net/?f=Pressure%3D%5Cfrac%7BnRT%7D%7BV%7D%3D%5Cfrac%7BmassXRT%7D%7BVXmolarmass%7D)
![Pressure=\frac{densityXRT}{molarmass}](https://tex.z-dn.net/?f=Pressure%3D%5Cfrac%7BdensityXRT%7D%7Bmolarmass%7D)
![molarmass=\frac{densityXRT}{Pressure}=\frac{1.5328X0.0821X298}{1}=37.50](https://tex.z-dn.net/?f=molarmass%3D%5Cfrac%7BdensityXRT%7D%7BPressure%7D%3D%5Cfrac%7B1.5328X0.0821X298%7D%7B1%7D%3D37.50)
Thus molar mass of gas is 37.50g/mol
