Answer:
1.26 moles
Step-by-step explanation:
Applying Avogadro's constant.
1 mole of every substance, has a particle of 6.02×10²³
From the question,
If,
1 mole of Neon contains 6.02×10²³ particles
Therefore,
x moles of Neon will contain 7.6×10²³ particles
x = (7.6×10²³)/(6.02×10²³)
x = 1.26 moles.
Hence the number of moles of Neon present is 1.26 moles
