Question

Calculate the number of H atoms present in 5 moles of ethane molecule.​

Answer 1

Answer:

There are six atom of hydrogen in each molecule of C2

H6 .so hence 1 mole C2 H6 will have 6 mole of

hydrogen atoms.so easily we can find the hydrogen atoms in 5 molecules.

We also know that 1 mole of a atom contain 6.02*10^23

(avagadro constant)

so in 5 molecules hydrogen there will be atom = 6.02*10^23 *

5 = 3.01*10^24 atoms

So the 5 hydrogen atom in ethane will have 6.02*10^23 atoms
