1.The molecular masses of Carbon is 12 and Oxygen is 16 therefore the mass of Carbon dioxide is 12+16+16= 44 (You have to double oxygen because there are two atoms of oxygen in CO2). The mass of oxygen is 16 but O2 is 32g/mole and the mass of helium is 4/mole. I also, noticed that all of these gasses are located on the right side of the periodic table. Gasses are very dense.
2. What is the mass of water H2O? Hydrogen 1 but there are two atoms so =2 Plus 16= 18. 18 is the mass of H2O. Water would sink because it doesn't have enough gas to float in the air.
