What is the mass of oxygen in a #233.0*g# mass of carbon dioxide?

Answer 1

Avery Adams

#"Mass of oxygen"-=170*g#.

We calculate the molar quantity of carbon dioxide is........

#(233*g)/(44.0*g*mol^-1)=5.30*mol#

Now, clearly, if there are #5.30*mol# #CO_2#, there are #10.6*mol# #"oxygen atoms"#. Do you agree?

And thus mass of oxygen #-=# #10.6*molxx16.0*g*mol^-1=??g#.

The molar mass of carbon dioxide is approximately 44.01 g/mol. The molecular formula for carbon dioxide is CO2, which consists of one carbon atom and two oxygen atoms. Therefore, the mass of oxygen in a 233.0 g mass of carbon dioxide is approximately 64.00 g.

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.
