Question
11. 2 × 10−2 mole of compound weigh 10g. What is molar mass of the compound_________
Select an answer
A. 500
B. 400
C. 200
D. 100
Solution
To find the molar mass of the compound, we need to use the formula:
Molar mass = Mass of the compound / Number of moles
Given in the problem, we have:
Mass of the compound = 10g Number of moles = 2 x 10^-2 moles
Substituting these values into the formula, we get:
Molar mass = 10g / 2 x 10^-2 moles = 500 g/mole
So, the molar mass of the compound is 500 g/mole. Therefore, the correct answer is A500.
