Problem 60822. Calculate the Number of Moles

Created by Hrishikesh Patil

Solve Later

The number of moles of a substance is calculated using the formula:
Mass (g) = Moles / Molar Mass (g/mol)​
Write a function calculate_moles(mass, molar_mass) that takes:
mass (in grams) of a substance
molar_mass (its molar mass in g/mol)
and returns the number of moles, rounded to three decimal places.

Mass is moles times molar mass, not moles divided by molar mass - or perhaps you meant to write Moles = Mass (g) / Molar Mass (g/mol).

Also, the test suite expects solutions to return 0 when a molar mass of zero is provided, not Inf.
