Question

Which has the maximum number of molecules among the following ? (A) 44 g CO 2 (B) 48 g O 3 (C) 8 g H 2 (D) 64 g SO 2

Tardigrade Admin · Accepted Answer

44 g CO 2=1 mol CO 2=NA molecules of CO 2 48 g O 3=1 mol O 3=NA molecules of O 3 8 g H 2=4 mol H 2=4 × NA molecules of H 2 64 g SO 2=1 mol SO 2=NA molecules of SO 2

Q. Which has the maximum number of molecules among the following ?

$44 g C O_{2}$

$48 g O_{3}$

$8 g H_{2}$

$64 g S O_{2}$

$44 g C O_{2} = 1$ mol $C O_{2} = N_{A}$ molecules of $C O_{2}$
$48 g O_{3} = 1$ mol $O_{3} = N_{A}$ molecules of $O_{3}$
$8 g H_{2} = 4$ mol $H_{2} = 4 \times N_{A}$ molecules of $H_{2}$
$64 g S O_{2} = 1$ mol $S O_{2} = N_{A}$ molecules of $S O_{2}$
