Answer:
A saturated sraight-chain hydrocarbon with two carbons is ethane.
Explanation:
Saturated hydrocarbons are called as alkanes with general formula where n=1,2,3,4......
Now, as it contains two carbon atoms therefore name of this compound should contain a prefix "eth". Also a suffix "ane" will come due to the fact that it is a saturated hydrocarbon.
So, molecular formula of this compound is
Structure of this straight chain compound has been attached below.

Answer: There are 3.2 moles of gas if you have a volume of 38.0 L under a pressure of 1430 mmHg at standard temperature.
Explanation:
Given: Volume = 38.0 L
Pressure = 1430 mm Hg (1 mm Hg = 0.00131579 atm) = 1.9 atm
Temperature = 273.15 K
Using ideal gas equation, the moles of gas will be calculated as follows.
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T =temperature
Substitute the values into above formula as follows.
Thus, we can conclude that there are 3.2 moles of gas if you have a volume of 38.0 L under a pressure of 1430 mmHg at standard temperature.

is directly related to the ideal gas law.
The ideal gas law states that:
. Rewriting this gives:
. R is the universal gas constant, so its value is fixed. For a given sample, n is the number of moles of the gas, so its value would be fixed too. This means that the value of 
would be a fixed constant as well. Therefore, whatever the initial value 
is, it should be equal to the final value
