A vessel contains 1.6g of dioxygen at STP(273.15k,1atm pressure). The gas is now trasnferred to another vessel at constnat temperature. Whre pressure becomes half of the original pressure. Calculate
( a) Volume of the new vessel.
(b) number of molecuels of dioxygen.

Explanation

To solve the problem step by step, we will follow the outlined approach in the video transcript.

### Step 1: Calculate the Volume of the Gas at STP

We start with the information given:
- Mass of dioxygen (O₂) = 1.6 g
- Molar mass of O₂ = 32 g/mol (since O has an atomic mass of 16, and O₂ has two oxygen atoms: 16 * 2 = 32 g/mol)
- At STP (Standard Temperature and Pressure), 1 mole of gas occupies 22.4 liters.
