Step 1

Given data here,

The formula of butane is C4H10.

The molecular weight of butane is 58.1 g/mol.

so, the calculation of number of moles of butane in present in 2.00 g is as follows: help_outlineImage Transcriptioncloseamount of butane number of moles of butane molecular mass butane 2.00g 58.1g/mol =0.0344 mol fullscreen
Step 2

One mole of butane contains 6.022×1023 molecules.

The calculation of the number of molecules present in 0.0344 moles of butane is as follows: help_outlineImage Transcriptionclose1 mole of butane 6.022 x 10"mole cule 0.0344 moles of butane 0.0344 x6.022 x 102molecule =2.07x102molecule fullscreen
Step 3

one molecule of butane contains 4 atoms of carbon.

The calculation of number of ...
