The treatment of CH3OH with CH3MgI releases 1.04 ml of a gas at STP. The mass of CH3OH added is:
Correct answer: A. 1.485 mg
- A. 1.485 mg
- B. 2.98 mg
- C. 3.71 mg
- D. 4.47 mg
Explanation
To solve this problem, first calculate the number of moles of gas released at STP using the ideal gas law equation. Then, use the stoichiometry of the reaction to determine the mass of CH3OH added. The correct answer is 1.485 mg, which is obtained through accurate calculations based on the given data and stoichiometry principles. The other options do not align with the correct calculations and are therefore incorrect.
