What is the molar mass of MGS?
I am currently studying the properties of various compounds in my chemistry class, and I’ve come across magnesium sulfide, often represented by the formula MGS. Can you help me determine the molar mass of MGS? I understand that to calculate this, I need to know the individual atomic masses of magnesium and sulfur, and then sum them appropriately based on their proportions in the compound. Could you provide a detailed breakdown of how to arrive at the molar mass, including the atomic weights you use? Thank you!
Answer
The molar mass of magnesium sulfide (MgS) can be calculated by adding the molar masses of its constituent elements: magnesium (Mg) and sulfur (S).
- Magnesium (Mg) has an atomic mass of approximately 24.31 g/mol.
- Sulfur (S) has an atomic mass of approximately 32.07 g/mol.
To find the molar mass of MgS, we add the atomic masses of magnesium and sulfur:
[ \text{Molar mass of MgS} = \text{Molar mass of Mg} + \text{Molar mass of S} ]
[ \text{Molar mass of MgS} = 24.31 \, \text{g/mol} + 32.07 \, \text{g/mol} ]
[ \text{Molar mass of MgS} = 56.38 \, \text{g/mol} ]
Therefore, the molar mass of magnesium sulfide (MgS) is 56.38 g/mol.
