Fill in the table with the volume of each sample. Use the periodic table to find the molar mass of each molecule. Then calculate the mass of the gas in each balloon.Periodic TableFirst, compare the two oxygen samples. Consider how volume relates to the number of moles. Now compare the two gases with the same volume. Is there a relationship between volume and mass?

1) First let's calculate the molar mass of O₂ and H₂:

O₂: (16x2) = 32 g/mol (for both oxygen 1 and 2)

H₂: (1x2) = 2 g/mol

2) Now let's calculate the mass of gas sample (g) of:

Oxygen 1:

mass = mole x molar mass

mass = 1 x 32 = 32 g

Mass of Oxygen 1: 32 g

Oxygen 2:

mass = mole x molar mass

mass = 2 x 32 = 64 g

Mass of Oxygen 2: 64 g

Hydrogen:

mass = mole x molar mass

mass = 1 x 2 = 2 g

Mass of Hydrogen: 2 g

For the two oxygen samples, if the number of moles double, the mass double and the volume also double.

But the two gases of the same volume have different masses (Hydrogen 2 g and

oxygen 32 g). So there is no relationship between volume and mass for different gases.
