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
Answer:
Periods on the periodic table of elements
Explanation:
In the periodic table of elements, there are seven horizontal rows of elements called periods. The vertical columns of elements are called groups, or families. (See also The Periodic Table: Metals, Nonmetals, and Metalloids.) In each period (horizontal row), the atomic numbers increase from left to right.
Answer:
an increasng atomic number/ increasing proton count
Explanation:
Answer:
Since the relationship between amino acid and codon bases would be the values of 3 nitrogenous bases per 1 amino acid.
knowing this relationship what you would do is simply multiply 146 x 3 to find the number of codon bases which would be C. 438.
