How many moles is 20 grams of CO2?
0.45 molesThe correct answer is 0.45 moles.
What is not correct 22 grams of CO2?
1 CO2 contains 2 atoms of oxygen , hence 1 mole CO2 contains 2 moles of oxygen and therefore moles of oxygen atoms or g-atoms of oxygen are 0.5x2 = 1 g-atom or 1 mole. Hence the incorrect option is (2).
How many moles are in 16g of CO2?
0.5 molesSo 16 g of O2 have 22 g of CO2 or 0.5 moles of it. Very simple as one mole is equal to twelve items so one mole CO2 is 44g here out of which 32g is O2 means if oxygen is 16g then CO2 must be 22g so it is clear that CO2 is 22g as we have to convert it into moles it is 12/22 =0.5 moles which is the answer.
