How many moles of neon (Ne, 20.18 g/mol) are in 68.4 grams of neon ?
[?] moles
The Correct Answer and Explanation is :
The number of moles of neon (Ne) in 68.4 grams is approximately 3.39 moles.
Explanation:
To calculate the number of moles of an element or compound, we use the formula:
[
\text{Moles} = \frac{\text{Mass (grams)}}{\text{Molar Mass (g/mol)}}
]
In this case, we are asked to calculate the moles of neon (Ne), which has a molar mass of 20.18 g/mol. This value indicates how many grams of neon are in one mole of the substance.
Given that we have 68.4 grams of neon, we can plug this into the formula along with the molar mass:
[
\text{Moles of neon} = \frac{68.4 \, \text{grams}}{20.18 \, \text{g/mol}} = 3.39 \, \text{moles}
]
This result tells us that 68.4 grams of neon corresponds to approximately 3.39 moles of neon atoms. This is because one mole of neon weighs 20.18 grams, so 68.4 grams would contain about 3.39 moles of neon atoms.
