Question

which contain more atoms 1 g of butene or 1g of dinitrogen or 1g of Na or 1g of water​

Answer 1

Given:

1 gram of Butene, 1 gram of dinitrogen, 1 gram of Na and 1 gram of water​

To Find:

Which of these contains more atoms

Solution:

The formula for Butane is C4H10 and the atom numbers in the compound are 14.

The molar mass is 58. Thus,

Number of moles = 1/58 = 0.0172

Number of Molecules = 6.023×10 ` 23  × moles

= 6.023 × 10`23  × 0.0172

= 1.038 × 10`22

Total number of atoms = number of atoma in compound × number.of molecules

= 14 × 1.038 × 10`22

= 1.453 × 10`23  in Butane

Answer: Among the given options 1 gram of butene consists of maximum atoms.
