Question

Calculate the no.of molecules in each of following 1gn2 1g co2

Answer 1

Answer:

Explanation:

To calculate the number of molecules in one gram of Nitrogen and one gram of carbon dioxide....

In order to calculate it we can use the Avogadro number..

The Avogadro number is=

6.022 x 10²³

The number of molecules of CO2 in one gram of CO2 is

1 x 6.022x 10²³/44

Here 44 is the one mole of carbon dioxide..

The number of molecules in 1 gram of carbon dioxide is= 0.136 x 10²³

= 13.6 x 10²¹ molecules

In a very similar way one mole of nitrogen is equals to 14 g

Thus the number of molecules in one gram of nitrogen is =

1 x 6.022 x 10²³/14

= 43 x 10²¹ molecules

Does the final answer is.....

One gram of carbon dioxide contains 13.6 x 10²¹ number of molecules.

And one gram of Nitrogen contains 43 X 10²¹ number of molecules

Hope it helps you....
