Predict the mass possessed by certain number of oxygen atoms which is

1.	Predict the mass possessed by certain number of oxygen atoms which is equal to the number of molecules present 1g of hydrogen gas?
Answer» Mass of oxygen atoms = number of molecules present 1g of hydrogen gas Number of molecules in 1g H₂ = 1/2 mole ⇒ 1/2×6.022 × 10₂₃atoms ⇒ 3.01 × 10²³ Thus, the mass possessed by certain number of oxygen atoms is 3.01 × 10²³

Predict the mass possessed by certain number of oxygen atoms which is equal to the number of molecules present 1g of hydrogen gas?

Answer»

Mass of oxygen atoms = number of molecules present 1g of hydrogen gas

Number of molecules in 1g H₂ = 1/2 mole

⇒ 1/2×6.022 × 10₂₃atoms

⇒ 3.01 × 10²³

Thus, the mass possessed by certain number of oxygen atoms is 3.01 × 10²³
