Question

Calculate the number of moles of neon gas in 8.15 x 10^24 atoms of neon gas.

Answer 1

Answer:

13.5 moles of Ne

Explanation:

1 mole of any gas contains  6.02 x 10²³ atoms of gas

6.02 x 10²³ atoms of neon is equal to 1 mole of neon .

8.15 x 10²⁴ atoms of neon is equal to  1 x 8.15 x 10²⁴ / 6.02 x 10²³ moles

= 8.15 x 10²⁴ / 6.02 x 10²³ mole o neon

= 13.5 moles of Ne .
