Question

What is the number of molecules present in 4.48 L of carbon dioxide at STP?​

Answer 1

Answer:

Molecular mass of CO2 is 44g/mole

So 44 g of CO2 = 1mole molecules

4.4g will be 0.1 mole molecules

At STP 22.4 L hydrogen gas is equal to 1 mole molecules

For 2.24L = 0.1 mole molecules

Totel molecules = 0.1+0.1=0.2 mole

So totel molecules in container is 0.2mole
