The fuel used in many disposable lighters is liquid butane, c4h10. butane has a molecular weight of 58.1 grams in one mole. how many carbon atoms are in 1.00 g of butane?

Answer : The number of carbon atoms present in butane are

Explanation : Given,

Molar mass of = 58.1 g/mole

Mass of = 1.00 g

First we have to calculate the number of moles of butane.

Now we have to calculate the number of carbon atoms present in butane.

In butane, there are 4 atoms of carbon and 10 atoms of hydrogen.

As we know that, 1 mole of substance contains number of atoms.

As, 1 mole of butane contains number of carbon atoms.

So, 0.0172 mole of butane contains number of carbon atoms.

Therefore, the number of carbon atoms present in butane are

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
