The formula of DMASO is [tex][(CH_3)_2 (SO) ][/tex]
[tex]Mass = 7.14 * 10^3 g[/tex]
[tex]Molar mass = 78 g[/tex][tex]78 g DMSO contains = 6.02 * 10^23 atoms[/tex][tex]7.14 * 10^3 g contains = (6.02 * 10^23 /78) * 7.14 * 10^3 atoms[/tex]
[tex]= 0.55 * 10^26 atoms[/tex]
As, there are 2 carbon are present in DMSO along with 1 sulfur and oxygen and it also contains 6 hydrogen.
[tex]Number of C present in DMSO = 0.55 * 10^26 * 2 = 1.102 * 10^26 carbons[/tex]
[tex]Number of S present in DMSO = 0.55 * 10^26 * 1 = 0.55 * 10^26 sulfur[/tex]
[tex]Number of H present in DMSO = 0.55 * 10^26 * 6 = 3.306 * 10^26 hydrogen[/tex]
[tex]Number of O present in DMSO = 0.55 * 10^26 * 1 = 0.55 * 10^26 oxygen[/tex]
