Which of the following contain maximum number of molecules at STP 100g of caco3 44.8l of o3 2g of h2 16g of o2

Q. Four cylinders are filled with 11.2 L of ${\text{H}}_2$, 5 L of ${\text{O}}_2$, 22.4 L of ${\text{N}}_2$ and 8 L of ${\text{Cl}}_2$ gases. Which cylinder contains the maximum number of molecules at STP?

Q. You are given sample of $1{\text{cm}}^3$ of $H_2$, $1{\text{cm}}^3$ of $O_2$ and $1{\text{cm}}^3$ of $C{l}_2$ which are at STP. The sample which has maximum number of molecules is

Q. Assertion :$16$ g each of $O_2$ and $O_3$ contains $\frac{N_A}{2}$ and $\frac{N_A}{3}$ atoms respectively. Reason: $16$ g each of $O_2$ and $O_3$ contains same number of atoms.

Q. You are given sample of $1{\text{cm}}^3$ of $H_2$, $1{\text{cm}}^3$ of $O_2$ and $1{\text{cm}}^3$ of $C{l}_2$ which are at STP. The sample which has maximum number of molecules is

Q. $A,B$ and $C$ are three cylinders of volume 11.2 L each. $H_2,O_2$ and $N_2$ gases at STP are filled in $A,B$ and $C$ respectively.
