Final answer:
The mass of 0.1000 mole of Argon gas is 3.995 grams when calculated using the molar mass of Argon, which is approximately 39.948 g/mol. None of the options provided exactly match this result, but option C would be correct for the mass of 1 mole, not 0.1000 mole.
Step-by-step explanation:
The mass of 0.1000 mole of Argon gas is determined by multiplying the number of moles by the molar mass of Argon. As per the periodic table, the molar mass of Argon is approximately 39.948 g/mol. Therefore, to find the mass of 0.1000 mole of Argon, we multiply 0.1000 mole by 39.948 g/mol, which results in 3.995 grams.
This calculation is based on the principle that the mass in grams of one mole of a substance is numerically equivalent to its molar mass. As Argon has a molar mass of 39.948 g/mol, for 0.1000 mole, the mass would be a tenth of that since 0.1000 mole is one-tenth of a mole.
So, the correct answer to the question is: 3.995 grams, which is not listed among the options provided. However, based on the closest value, option C (39.95 grams) would be correct if the question intended to ask for the mass of 1 mole of Argon gas, not 0.1000 mole.
