Answer : The molecular weight of a gas is, 128.9 g/mole
Explanation : Given,
Density of a gas = 5.75 g/L
First we have to calculate the moles of gas.
At STP,
As, 22.4 liter volume of gas present in 1 mole of gas
So, 1 liter volume of gas present in
mole of gas
Now we have to calculate the molecular weight of a gas.
Formula used :

Now put all the given values in this formula, we get the molecular weight of a gas.


Therefore, the molecular weight of a gas is, 128.9 g/mole
Answer:
Structural formula
Explanation:
This is because structural formula is use to show or indicate chemical bonds that are present between atoms of molecules. structural formula comprises of symbols that represent the atoms which are connected by short lines which indicate the presence chemical bonds which could be single line, double lines or even triple lines.
Explanation:
The given reaction equation is as follows.
The value of
= 59.1 kJ/mol
We know that
,
or, 
= -(\frac{59.1 kJ/mol}{(8.314 \times 10^{-3} kJ/mol.K \times 310 K))}[/tex]
= -22.93
or,
=
Therefore,
=
= 
Therefore, we can conclude that the value of
in the intestinal tract is
.
