Best ResponseYou've already chosen the best response.1because by definition of mole ,the molecular/atomic mass (in grams) of a certain molecule contains one mole of it.argon has atomic mass of 40g..hence 40g of argon is its 1 mole..

Best ResponseYou've already chosen the best response.0There is 39.9g/mol of molar mass for Argon, you can arrange a ratio to cancel out the ones you don't need. \[100\cancel{g~Ar} \times \frac{1mol~Ar}{39.9\cancel{g~Ar}}=2.5mol~Ar\]

Best ResponseYou've already chosen the best response.0Yep, Sam is correct...anytime you want to know the moles of anything, just look at the molar mass of the element and repeat his procedure! :o)
