How many molecules are found in 20 grams of oxygen gas

1 grams Oxygen to mol = 0.0625 mol 10 grams Oxygen to mol = 0.62502 mol 20 grams Oxygen to mol = 1.25005 mol

How many moles of oxygen atoms are there in 20 g of O2? - Quora. Look, 32 grams of O2 contains 1 mole of O2 molecule and 1 molecule of O2 have two O atom so we can say that 32 grams of O2 contains 2 mole of O atoms , So 1 grams contains 2/32 moles of O atoms So in 20 grams it contains (2*20)/32 = 1.25 moles of O atoms.

Explanation:number of moles = given mass / molar mass

= 20/32

= 5/8

number of molecules = no. of moles × Avogadro no.

= 5/8 × 6.022×10²³

= 3.76 × 10²³ mllecules
