Explanation:
NO OF MOLES= GIVEN WEIGHT/ MOLAR MASS
NO OF MOLES = 4.4/44 = 0.1 MOLE
NO OF MOLES = GIVEN VOLUME /22.4
SO VOLUME = NO OF MOLES× 22.4
VOLUME = 0.1×22.4= 2.24 litre
no of molecules = no of moles × avagadro number
no of molecules= 0.1×6.022 ×10²³
no of molecules = 6.022×10²²or 0.6022×10²³
