calculate no.of.atoms in 0.5 moles of ethane
Answers
Answer:
One mole of carbon contains 6.022×10²³ atoms of carbon.
So, 0.5 mol of carbon will contain 6.022×12²³/2 = 3.011×10²³ atoms.
O.5 mol C12 x 6.022x10^23 = 3.011x10^23atoms of C12. The trick is if you have number of atoms in this many atoms only have 1 step. If it was atoms in h2o then their would be 3 atoms per h2o molecule and thus 3x as many in a half a mol of C12

Answer:
1 mole of C2H2=12×2+2×1=24+2=26g
1mole of C2H2 is 26g then 0.5 mole of C2H2 is =26×0.5=13g
