Question

Identify the pair of gases which have same number of molecules at S.T.P.?

• A. \(11\ \text{g of }CO_2\) and \(14\ \text{g of }N_2\)
• B. \(16\ \text{g of }O_3\) and \(16\ \text{g of }CH_4\)
• C. \(5\ \text{g of }H_2\) and \(40\ \text{g of }CH_4\)
• D. \(28\ \text{g of }N_2\) and \(22\ \text{g of }CO_2\)

Hint:

To compare number of molecules, compare number of moles using \(n=\frac{w}{M}\).
