The maximum number of molecules is present in (1) 15 L of water at STP (2) 15 L of H2O gas at STP (3) 15 g of ice (4) Same in all

Answered by admin @ 29/08/2021

(1) 15 L of water at STP has highest number of molecules.

Explanation:

The given three options are as follows:

At STP, 15 L of water; 15 L of $H_2O$ ; and 15 g of Ice.

If we observed, in three options $H_2O$ is present in three different states.

At standard pressure and temperature, the liquid state has maximum density hence it has high number of atoms. The density of liquid state of any compound is equal to the density of gas and solid forms at STP.

Therefore, 15 L of water will have maximum number of molecules then compared to 15 gm of ice and 15 L of $H_2O$ gas.
