A certain gas 'X' occupies a volume of `100 cm^(3)` at STP and weighs 0.5 g. Find its relati ve molecular mass.

Explanation

To find the relative molecular mass of the gas 'X', we can follow these steps:

### Step 1: Understand the volume of gas at STP
At Standard Temperature and Pressure (STP), 1 mole of any gas occupies approximately 22.4 liters (or 22,400 cm³).

### Step 2: Convert the volume of gas to liters
Given that the volume of gas 'X' is 100 cm³, we can convert this to liters:
\[
