Using ideal gas equation,
Here,
P denotes pressure
V denotes volume
n denotes number of moles of gas
R denotes gas constant
T denotes temperature
The values at STP will be:
P=1 atm
T=25 C+273 K =298.15K
V=663 ml=0.663L
R=0.0821 atm L mol ⁻¹
Mass of gas given=1.25 g g
Molar mass of gas given=?
Putting all the values in the above equation,
Molar mass of the gas=46.15
Answer:
Carboxylic acids react with diazomethane to produce methyl esters.
Explanation:
Diazomethane has a high reactivity and is used to produce methyl esters with carboxylic acid in a immediately reaction, carried out at room temperature in the absence of catalysts.
As we can see in the image below
The subproduct is Nitrogen; knowing this, we must be careful with the production of this gas, and do the process in a vented place
