Question

solve and explain it​

Answer 1

Molar mass of O₂ = 16*2 = 32g

Mass of Oxygen with given no of molecules:

                                 = No of moles * Molar Mass

                                 = (No of molecules/ Avogadro No)*Molar Mass

                          = (10.044*10²⁵/ 6.022*10²³)*32

                          = 1.66 * 10² * 32

                          =53.12 * 10²

                           = 5312g of O₂ is present
