Final answer:
The sample of krypton has a greater mass compared to the sample of neon.
Step-by-step explanation:
In order to determine which sample has the greater mass, we need to compare the molar masses of krypton and neon. The molar mass of a substance is the mass of one mole of that substance. From the periodic table, we find that the molar mass of krypton is approximately 83.80 g/mol, while the molar mass of neon is approximately 20.18 g/mol.
Since mole-to-mole comparisons can be made using the same number of moles, we can say that if we have one mole of krypton and one mole of neon, the krypton sample would have a greater mass because its molar mass is greater.
This is because the molar mass of krypton (Kr) is greater than that of neon (Ne). From the periodic table, we know that the atomic mass of krypton is approximately 83.798 g/mol, while that of neon is about 20.1797 g/mol. Since the number of moles is the same, multiplying the molar mass by the number of moles will give us the mass of each sample. The mass of the krypton sample will be greater because its molar mass is higher than that of neon.
