<u>Answer:</u> The mass of morphine is 0.059 grams
<u>Explanation:</u>
To calculate the number of moles for given molarity, we use the equation:
Molarity of sulfuric acid solution = 0.0116 M
Volume of solution = 8.92 mL
Putting values in above equation, we get:
The given chemical equation follows:
By Stoichiometry of the reaction:
1 moles of sulfuric acid reacts with 2 moles of morphine
So, of sulfuric acid will react with =
To calculate the mass of morphine for given number of moles, we use the equation:
Molar mass of morphine = 285.34 g/mol
Moles of morphine =
Putting values in above equation, we get:
Hence, the mass of morphine is 0.059 grams
