Question

Which among the following has maximum number of molecules?

Choose answer:

22 g CO2


40 g SO3


10 g CH4


20 g NO2

Answer 1

Answer:

10 g ch4 is right

Explanation:

ok ffgh

Answer 2

$no \: of \: moles = \frac{given \: mass}{molar \: mass}$

no. of moles = 22 / [12+(2×16)]

of CO2 = 22 / 44

= 0.5

no. of moles = 40 / [32+(3×16)]

of SO3 = 40 / 80

= 0.5

no. of moles = 10 / [12+(1×4)]

of CH4 = 10 / 16

= 0.625

no. of moles = 20 / [14+(2×16)]

of NO2 = 20 / 46

= 0.435

no. of moles is directly proportional to no. of molecules

hence, 10g of CH4 has maximum no. of molecules.
