Question

Find the number of moles and numbervof atoms of h and s in 10 mole of h2s

Answer 1

Answer:

let X be the number of moles H in 10 moles of H2S

1 mole of H2S -------> 2 moles of H

10 moles of H2S------> X moles of H

X=10×2

(X=20)

no of atoms of H in 10 moles of H2S can be found by using the formula

no of moles = no of atoms/Avagadro constant-----------------(1)

no of moles of H =no of atoms of H/Avagadros constant

No of atoms of H=no of moles of H × avagadros constant

= 20×6.022×10*23

=(12.044×10*24)

Let Y be the number of moles of S in 10 moles of H2S

1 mole of H2S --------> 1 mole of S

10 moles of H2S -------> Y moles of S

(Y=10 moles S)

by using -----(1)

no of atoms of S = no of moles of S × avagadros constant

= 10× 6.022 ×10* 23

=(6.022×10*24)
