What molar quantity is associated with a #0.44*g# mass of #"carbon dioxide"#?

Answer 1

We solve the quotient.......#"mass"/"molar mass"# to get the number of moles........

And so here.........we gets..........#(0.44*g)/(44.01*g*mol^-1)=0.010*mol# with respect to #CO_2#.

But one mole specifies by definition, #N_A, "Avogadro's number"# of molecules, where #N_A-=6.022xx10^23*mol^-1#.

And thus number of individual #CO_2# molecules is given by the product..#6.022xx10^23*mol^-1xx0.010*mol-=6.022xx10^21# individual molecules of #CO_2#. How many carbon atoms, and how many oxygen atoms does this molar quantity represent?

The molar quantity associated with a 0.44 g mass of carbon dioxide is approximately 0.01 moles, calculated using the molar mass of carbon dioxide (CO2), which is approximately 44.01 g/mol.

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.
