Answer:

0.059 moles are present in 2.6 g of CO₂

Explanation:

Molar mass is the mass of one mole of a substance, which can be an element or a compound. That is, it is the amount of mass that a substance contains in one mole.

In this case, the mass of each element being:

  • C: 12 g/mole
  • O: 16 g/mole

then the molar mass of the compound is:

CO₂=  12 g/mole + 2*16 g/mole= 44 g/mole

Then you can apply the following rule of three: if by definition of molar mass 44 grams of CO₂ are present in 1 mole, 2.6 grams will be present in how many moles?

[tex]amount of moles=\frac{2.6 grams*1 mole}{44 grams}[/tex]

amount of moles= 0.059 moles

0.059 moles are present in 2.6 g of CO₂
