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.

Options

A. Both A and R are true and R is the correct explnanation of A.
B. A is true but R is false.
C. A is false but R is true.
D. Both A and R are flase.

Explanation

To solve the assertion and reason question, we will break it down step by step.

### Step 1: Understand the Assertion and Reason
- **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.

### Step 2: Analyze the Reason
The reason states that the empirical formula represents the simplest whole number ratio of the atoms in a compound. This is a true statement. The empirical formula is derived from the molecular formula by reducing the subscripts to their simplest form.
