moles of HCl=mass/GMM
=> moles=73/(1+35.5)
=>moles=2
No of molecules in HCl=moles x Avogadro's Number(Na)
=> no of molecules in HCl=2xNa
According to Question,
No of atoms in Oxygen=2Na
moles of oxygen=No of atoms/ Avogadro's Number
=>moles=2Na/Na=2 (Since Na got cancelled)
mass of Oxygen=moles x molecular mass
=>Required mass=2x16=32g
=> moles=73/(1+35.5)
=>moles=2
No of molecules in HCl=moles x Avogadro's Number(Na)
