15 moles of an unknown substance has a mass of 2308.94g. What is molar mass of the substance?SHOW ALL STEPS FOR FULL MARKS!
Solution
Step 1: Understand the question The question is asking for the molar mass of a substance. Molar mass is the mass of one mole of a substance and it is usually expressed in grams/mole (g/mol).
Step 2: Identify the given values The question provides the following information:
- The mass of the substance is 2308.94g
- The number of moles of the substance is 15 moles
Step 3: Use the formula for molar mass The formula for molar mass is:
Molar mass = Mass of the substance (in grams) / Number of moles
Step 4: Substitute the given values into the formula So, substituting the given values into the formula, we get:
Molar mass = 2308.94g / 15 moles
Step 5: Calculate the molar mass When you perform the division, you get:
Molar mass = 153.9296 g/mol
So, the molar mass of the substance is approximately 153.93 g/mol.
