Question

What will be number of atoms in 11.2 lit of so2 at ntp?

Answer 1

solution:

At ntp volume of 1 mol of gas is 22.4 L  

so as volume of SO2 at STP is 11.2 L thiss means that u have 0.5 mol of it  

and one mole of anything contains 6.022 * 10^23 atoms so 0.5 mol contains 3.011*10^23 atoms
