Question

What is the mass of molecule of oxygen in 22g of co2

Answer 1

The molecular mass (molar mass) of Carbon dioxide is 44 g, meaning thereby it contains 6.022 x 10^23 molecules of CO2. Since 1 mole of CO2 is 44 g... and you have 1/2 of a mole, you have one half the number of molecules in one mole; 6.02 x 10^23/ 2.
