(a). 1 mole of CO2 has mass = 44g
=> 2 moles of CO2 = 44 2 =88g

(b).2 N molecules of CO2 contain 44g
=> 2 N molecules of CO2 contain= 44 2 = 88g

Final answer:
(a). 1 mole of CO2 has mass = 44g
=> 2 moles of CO2 = 44 2 =88g

(b). 2 N molecules of CO2 contain 44g
=> 2 N molecules of CO2 contain= 44 2 = 88g
