Limestone is primarily a crystal form of caco 3 ​ . How many moles of oxygen are in a 1.25 mol sample of caco 3 ​ ? Only include the numerical value in your answer. Do not include units.

Respuesta :

As the molecular formula of CaCO₃ suggested, that there are 3 moles of oxygen are there in 1 mole of CaCO₃.

So in 1.25 mol of CaCO₃ contains=1.25 ×3 moles of oxygen  

                                                    =3.75  moles of oxygen

So there are 3.75  moles of oxygen are there in 1.25 mol of CaCO₃.

There are 3.75 moles of oxygen in a 1.25 mol sample of CaCO₃.

Limestone is primarily a crystal form of CaCO₃ (calcium carbonate). According to its chemical formula, the molar ratio of CaCO₃ to O is 1:3. The moles of oxygen in 1.25 moles of CaCO₃ are:

[tex]1.25 mol CaCO_3 \times \frac{3molO}{1molCaCO_3} = 3.75molO[/tex]

There are 3.75 moles of oxygen in a 1.25 mol sample of CaCO₃.
