Question

Convert into mole 12gm of oxygen 28gm of water 22gm of carbondioxide

Answer 1

Hey mate,
here is your answer ---------

Molar mass of O2 = 2 x 16 = 32 g

Number of moles in 12g O2 = Given mass/ Molar mass = 12/32 = 0.375 mole

 

Molar mass of CO2 = 12 + 16 x 2 = 12 + 32 = 44g

Number of moles in 22g CO2 = 22/44 = 0.5mole

Sorry I can't answer that 28 gm one....
Hope it helps you mate! : )
