11.2L of a gas at STP weighs 14.0g. The gas could be?

(A) N2O (B) NO2 (C) N2 (D) CO​

Answer 1

Answer:

$\huge \underline \mathbb \color{aqua}Answer$

11.2L of an ideal gas at STP =0.5 moles.

It could be any gas that have molar mass equal to or closer to 28g/mole. (Nitrogen, molar mass=28g/mol)

⟹ The gas could be N2.

Answer 2

$\huge \sf \pink{Answer:-}$

• It could be any gas that have molar mass equal to or closer to 28g/mole. (Nitrogen, molar mass=28g/mol)

$\blue{\to}$ The gas could be N2.
