How many valence electrons are in a structure with the formula c3h3nos?

C₃H₃NOS,

Number of valence electron of carbon: 4

Number of valence electron of hydrogen : 1

Number of valence electron of nitrogen: 5

Number of valence electron of sulfur: 6

Total number of valence electrons in C₃H₃NOS

=no. of carbon atoms*4+1*no. Of hydrogen atom+5*no. of nitrogen atom+6*no. of oxygen atom + 6*no. of sulfur atom

=3*4+1*3+5*1+6+6

=12+3+5+6+6

=32

So, total number of valence electrons in C₃H₃NOS is 32.
