How many moles of neon are in 7.6 x 10^23 in sig figs

1.26 moles

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
