Thave 7.6 x 1023 particles of neon. How many moles of neon do I have?

1.26moles

Explanation:

To get the number of moles (n) in an element, we divide the number of molecules of the element by Avagadro number (6.02 × 10^23)

n = no. of molecules ÷ nA (6.02 × 10^23)

According to this question, number of molecules of Neon (Ne) is 7.6 x 10^23 particles.

n = 7.6 x 10^23 ÷ 6.02 × 10^23

n = 7.6/6.02 × 10^(23-23)

n = 1.26 × 10^0

n = 1.26moles
