Question

Which has maximum no. of molecules among the following and why? a)44g of CO2 b)48g of O2 c)8g of H2 d)64g of SO2

Answer 1

c) 8g h2 contains max no of molecules
it contains 4 x 6.022 x 10 power 23 molecules

Answer 2

no. of moles = W/M = weight/(molecular weight)
(a) no. of moles = 44/44 = 1
(b)no. pf moles = 48/32 = 1.5
(c) no. of moles = 8/2 =4
(d)no. of moles = 64/64 =1
Hence, (c) have the maximum molecules
4 moles, i.e. 4×6.023×10^23 molecules
