How many number of moles in co2 contain 8.0g of oxygen?
Mass of Oxygen = 8 g
Molar mass of Oxygen, O2 = 32 g mol-1
Number of moles of Oxygen = 8 / 32
= 0.25 moles
1 mole of CO2 contains one mole of Oxygen so 0.25 mole of oxygen is present in 0.25 moles of CO2.
Molar mass of Oxygen, O2 = 32 g mol-1
Number of moles of Oxygen = 8 / 32
= 0.25 moles
1 mole of CO2 contains one mole of Oxygen so 0.25 mole of oxygen is present in 0.25 moles of CO2.
