How many moles is equivalent to 8.23 x 1022 molecules of nitrogen dioxide: NO2 (Mw. 46.01 g/mol)?

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

0.137moles is equivalent to 8.23 x 10²² molecules of nitrogen dioxide (NO2).

HOW TO CALCULATE MOLES:

The number of moles in a substance can be calculated by dividing the number of molecules in the substance by Avogadro's number. That is;

no. of moles = no. of molecules ÷ 6.02 × 10²³

According to this question, 8.23 x 10²² molecules of nitrogen dioxide (NO2) were given. The number of moles can be calculated as follows:

no. of moles = 8.23 x 10²² ÷ 6.02 × 10²³

no. of moles = 1.37 × 10²²-²³

no. of moles = 0.137moles

Therefore, 0.137moles is equivalent to 8.23 x 10²² molecules of nitrogen dioxide (NO2).
