If one gram of sulphur dioxide contains x molecules what will be the number of molecules in 1g of methane

Explanation:

The ratio of molecules in sulphur dioxide and methane will be the same as the ratio of their moles. So, first of all we should find out the number of moles of sulphur dioxide in 1 gram of sulphur dioxide in 1 gram of sulphur dioxide, and the number of moles of methane in 1 gram of methane. This can be done as follows :

(i) The molecular formula of sulphur dioxide is

So,  mole of =

grams

Now, of sulphur dioxide mole

So, of sulphur dioxide = mole

Thus, we have mole of sulphur dioxide and it contains molecules in it. Now, since equal moles of all the substance contain equal number of molecules, therefore, mole of methane will also contain x molecules of methane.

(ii) Molecular formula of methan is

So, 1 mole of  = Mass of C + Mass of 4 H

Now, 16g of methane = 1 mole

So, 1 g of mathane = mole

We know that:

mole of methane contains = x molecules

So,  mole of contains will contain = molecules

= molecules

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
