How many moles is equivalent to 8.23 x 1022 molecules of nitrogen dioxide: no2 (mw. 46.01 g/mol)?

0.1367 moles of NO₂

Explanation:

The relation between moles and molecules, ions, or atoms is given by Avogadro Number (NA). Avogadro determined that 1 mol has 6.02x10²³ molecules, ions, or atoms. So:

1 mol of NO₂ 6.02x10²³ molecules of NO₂

x 8.23x10²² molecules of NO₂

By a direct simple three rule:

6.02x10²³x = 8.23x10²²

x = (8.23x10²²)/(6.02x10²³)

x = 0.1367 moles of NO₂
