Which gas occupies the highest volume at stp?
0.02 mol of o2
0.1 mol of cl2
1 mol of n2
2 mol of h2

Answer : The correct option is, 2 mole of

Solution :

As we know that,

At STP, 1 mole of gas occupy 22.4 liter volume of gas

That means the higher the moles of gas, highest volume will be the occupied by the gas.

From the given options, gas contains more number of moles as compared to another gas. So, 2 mole of gas occupies the highest volume at STP.

Hence, the correct option is, 2 mole of

The correct answer is D. Which is "2 mol."
