This means that 1 mole of carbon dioxide has a mass of 44.01 g . Oxygen has a molar mass of 16.0 g mol−1 , so 1 mole of oxygen atoms has a mass of 16.0 g . Therefore, carbon dioxide has a percent composition of 72.7% oxygen, i.e. for every 100 g of carbon dioxide you get 72.7 g of oxygen.

At STP, a mole of gas takes up 22.4 liters. So the dioxide carbon producted will be 0.67/2 moles. Or, it will be 15/2 = 7.5 liters.
113353
One molecule of CO2 contains one atom of carbon and two atoms of oxygen One mole of CO2 contains one mole of carbon atoms and two moles of oxygen atoms.
1182888
If we want to find the number of moles, we need to divide by the molar mass. So, the person exhales approximately 0.55 moles of carbon dioxide per hour.

The Number of molecules in 1 mole of Carbon Dioxide is equal to Avogadro's number which is equal to . The mass of 1 mole of or 1 molecule of is 44 units. Therefore mass of half a mole is 22 units.
422289
Using the formula number of moles = Mass/Mr 44/44=1 mole of CO2 present. (Mr of carbon dioxide is (2*16)+12=44 Now times by Abogadros constant: 1* 6.022*10^23=6.022*10^23 molecules of CO2 are present.
