Answer 1

pata nhi bhai practically experiment karke dekh le

Answer 2

Answer:

In H2S , there are 2 number of hydrogen atoms and 1 number of sulfur atom.

As we know that 1 mole is equal to the 1 gram atom

As, 1 mole of H2S contains 2×0.40=0.8 gram atoms of H

So, 0.40 mole of contains gram atoms of H

As, 1 mole of H2S contains 1 gram atoms of S

So, 0.40 mole of H2S contains 1×0.40=0.40 gram atoms of S

Therefore, 0.8 gram atoms of H and 0.4 gram atoms of S are present in 0.40 mole of H2S
