Explanation:
The IUPAC name of aspirin is 2-Acetoxybenzoic acid. It is composed of an acetoxy moiety and a benzoic acid moiety.
The compound can be hydrolysed under prolonged storage conditions to yield acetic acid which causes the vinegar like odour.
Also, one of the products of this hydrolysis bears a phenol group which reacts with FeCl3 to give a purple color.
<u>Answer:</u> The mass percent of nitrogen gas and hydrogen gas is 91.41 % and 8.59 % respectively.
<u>Explanation:</u>
To calculate the number of moles, we use the equation given by ideal gas equation:
PV = nRT
where,
P = Pressure of the gaseous mixture = 1.00 atm
V = Volume of the gaseous mixture = 24.62 L
n = number of moles of the gaseous mixture = ?
R = Gas constant =
T = Temperature of the gaseous mixture = 300 K
Putting values in above equation, we get:
We are given:
Total mass of the mixture = 13.22 grams
Let the mass of nitrogen gas be 'x' grams and that of hydrogen gas be '(13.22 - x)' grams
To calculate the number of moles, we use the equation:
<u>For nitrogen gas:</u>
Molar mass of nitrogen gas = 28 g/mol
<u>For hydrogen gas:</u>
Molar mass of hydrogen gas = 2 g/mol
Equating the moles of the individual gases to the moles of mixture:
To calculate the mass percentage of substance in mixture we use the equation:
Mass of the mixture = 13.22 g
Mass of nitrogen gas = x = 12.084 g
Putting values in above equation, we get:
Mass of hydrogen gas = (13.22 - x) = (13.22 - 12.084) g = 1.136 g
Putting values in above equation, we get:
Hence, the mass percent of nitrogen gas and hydrogen gas is 91.41 % and 8.59 % respectively.
