How many grams are in 4.35 moles of Ar?

Answer 1

Approx. #170# #g#.

Argon has a mass of #39.95# #g*mol^-1#. If there are 4.35 mol, then the mass is simply #4.35# #molxx39.95*g*mol^-1#. Note that as an inert gas, we quite properly assume that argon is atomic. What assumption would we make if the gas had been oxygen or nitrogen?

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
