What equation relates the mass of a gas to the number of moles?
Understand the Problem
The question is asking about the relationship between the mass of a gas (m), the number of moles (n), and molar mass (M) through a specific equation. The key concepts include the definitions of mass, moles, and molar mass in the context of gas laws in chemistry.
Answer
Molar mass (M) = Mass (m) / Number of moles (n).
The equation that relates the mass of a gas to the number of moles is derived from the definition of molar mass: Molar mass (M) = Mass (m) / Number of moles (n).
Answer for screen readers
The equation that relates the mass of a gas to the number of moles is derived from the definition of molar mass: Molar mass (M) = Mass (m) / Number of moles (n).
More Information
Molar mass is a useful property that represents the mass of one mole of a substance. The relationship helps in determining quantities like gas density and volumes under varying conditions using the Ideal Gas Law.
Tips
A common mistake is to confuse the ideal gas law with the direct relationship between mass and moles. Ensure clarity between these concepts and use the correct formulas.
