Question

There are 3.0115×10^23 atoms of H present in a container containing C3H6. Calculate the number of molecules of C3H6 present in the container.​

Answer 1

Hola

in one mole of propene (C₃H₆)

There are 6 moles of H atoms, and 3 moles of C atoms

in 3.0115 × 10²³ atoms, 0.5 moles of H atoms are present

So, the number of molecules of propene = 0.5/6 = 0.083 moles of propene

So, now, no. of molecules = 0.083 × 6.022 × 10²³ = 5.02 x 10²⁰ molecules
