What is the number of molecules of $SO_2$ present in $64 \ g$ of $SO_2$?

Sucrose has molecular formula $C_{12}H_{22}O_{11}$. How many moles of carbon atoms are present in its $34.2 \ g$ sample?

Which of the following substances consists of a total of $1 \ mol$ of atoms? (Molar mass of $NH_3 = 17 \ g/mol, H_2O = 18 \ g/mol, N_2 = 28 \ g/mol, CO_2 = 44 \ g/mol$)

If the number of moles of $CH_4$ is equal to the number of moles of $1.24 \, g$ of $SO_2$,then the weight of $CH_4$ will be ............ $g$.

Which has the maximum number of molecules among the following?

The mass of $4.48 \ dm^3$ of a certain gas is $5.6 \ g$ at $STP$. Assuming ideal behaviour,identify the probable gas from the following.
