Number of gram molecules of oxygen in 6.02 ×10²4 CO molecules is?

To find the number of gram molecules of oxygen in 6.02 × 10^24 CO molecules, we first need to determine the molar ratio of oxygen to carbon monoxide in the CO molecule.

The chemical formula for carbon monoxide is CO, which means that for every one molecule of CO, there is one atom of carbon and one atom of oxygen.

Therefore, the molar ratio of oxygen to carbon monoxide is 1:1.

Now, we can calculate the number of gram molecules of oxygen in 6.02 × 10^24 CO molecules:

Number of gram molecules of oxygen = Number of CO molecules / Avogadro's number

Number of gram molecules of oxygen = 6.02 × 10^24 / 6.022 × 10^23

Number of gram molecules of oxygen = 10

Therefore, there are 10 gram molecules of oxygen in 6.02 × 10^24 CO molecules.

Given:
Number of CO molecules = 6.02 × 10²⁴

1 mole of CO contains 1 mole of O atoms.

Therefore, number of moles of O atoms = 6.02 × 10²⁴ molecules/ 6.02 ×10²³ molecules/mol = 10 mol

Number of gram molecules of O = 10 g-moles
