Question

which has the maximum number of molecules among the following?
(a) 44g of CO2
(b) 44g of O2
(c) 8g of H2
(d) 64g of SO2

iska answer (b) h but plz koi bta do kese iska answer b h??​

Answer 1

Answer:

8g of H2 is the right answer

Answer 2

Correct option is C 8g of H2

The number of moles can be calculated from the ratio of the mass to the molar mass.

Maximum number of moles will corresponds to maximum number of molecules.

                                                

Moles of CO2 =

$\frac{44}{44} = 1 \: mol$

Moles of O3 =

$\frac{48}{48} = 1 \: mol$

Moles of H2 =

$\frac{8}{2} = 4 \: mol$

Moles of SO2 =

$\frac{64}{64} = 1 \: mol$

Hence, 8g H2  has the maximum number of molecules.
