Find the mass of the following:
(i) 6.022 x 10²³ number of O₂ molecules
(ii) 1.5 mole of CO₂ molecule.

Academic Chemistry NCERT Class 9

(i) 6.022 x 10²³ number of 02 molecules:

Mass of 1 mole of O₂molecule = 6.022 x 10²³ molecules = 32 g

(ii) 1.5 mole of CO₂ molecule:

Mass of 1 mole of C0₂ molecule = 6.022 x 10²³molecules = 44 g

Mass of 1.5 mole C0₂ molecule = 44 x 1.5 = 66 g
