Question 3 (1 point) Which contains the largest total number of atoms? O 1 mol C2H6 O2 mol CH4 O 3 mol H2O 06 mol He All contain the same number of atoms

Answer 1

* Conversion of moles to q-lom or Molecule:- cricinole) = No (No. of atom or molecule) NA C Aragdoo's Number ) NA =) 6.022 %1023 Nn' 1 mol of X = man moles 1 No. of atoms * If molecule is given than formula will be x mol of molecule NA (molecule) i mol of Molecue -* atom in moleculel I molecule X @ 1 ci) 1 mol Camo - Noof atoms 23 molecule mol fana 6.022 x 10 23 anos e 1 mol cine o atoms cano molecule Caha > - a + x 61022 X 1023x 8 atom of Cani 6.622 X 10 23 x 8 atoms of cah 4,817 x 1024 atoms of C2H6

> 1 23 (11) 2 mol enu ..2 motanu x 6.022x10 molecule a 5 atoms enu mol thy I molecule only = 2x6:022410 23x5 atoms of chy . - 10x 6.022 x 1023 atoms of chy s 6.022 x 1024 atoms of che 3 mol 23 (111) . 3 mol H2o. molto 6.022X10 molecule 1 i mol H20 B atoms H2O. 8d Moleerde no 3x6.022 x 1023 x 3 atoms of 120 9x 6.022 x 1023 atoms of H2O т пт 5.419 x1024 atoms of ho 6 mol he Cluj a s mot me a 6.022x10 23 atoms i molte 6X6.622 81023 atoms of ne - of - atom He 3.613X10"

so, in The the largest girrem total Number of atoms a option is in a mol cha с 022 Яto - atoms си, 2 та си, е (1) > (TI) (I) > (IV) y complete order
