Calculate oxygen atoms present in 8.8g co2 molecule...

Answer:

Given:

8.8 g of carbondioxide = moles of carbondioxide.

To find:

Number of O2 atom in CO2.

Explanation:

Molar mass of CO2:

44 g CO2 having 1 mol of O2 and 1 mol of CO2 having2 mol of O2.

Then,88 g of CO2 having 2 mol of O2 and 2 mol of CO2 having4 mol of O2.

So, the number of atoms can be counted by

number of atoms = no. of moles x Avogadro's number

so. the number of oxygen atoms are
