160619 Assertion (A) : The empirical mass of ethene is half of its molecular mass.
Reason (R) : The empirical formula represents the simplest whole number ratio of various atoms present in a compound.

1 Both \(A\) and \(R\) are true and \(R\) is the correct explanation of \(A\).
2 \(A\) is true but \(R\) is false.
3 \(A\) is false but \(R\) is true.

160620 Assertion (A) : 10 moles of \(\mathrm{CO}_{2(\mathrm{~g})}\) and 10 moles of \(\mathrm{H}_{2(\mathrm{~g})}\) have equal volumes under the same conditions of temperature and pressure.
Reason (R) : Equal volumes of all gases under the same conditions of temperature and pressure contain equal number of molecules ( or moles).

1 Both \(A\) and \(R\) are true and \(R\) is the correct explanation of \(A\).
2 Both \(\mathrm{A}\) and \(\mathrm{R}\) are true but \(\mathrm{R}\) is not the correct explanation of \(A\).
3 \(A\) is true but \(R\) is false.
4 Both \(A\) and \(R\) are false.
