Question 126703


if the number of propane atoms is {{{P}}}

{{{P =26}}}

if the number of hydrogen atoms is {{{H}}}


if the number of carbon atoms is {{{C}}}

then

{{{26 = H+C }}}

since

{{{H+6=3C }}}………. .=>… {{{H=3C-6 }}} ………..then


{{{26 = 3C-6 +C }}}

{{{26+6 = 4C }}}

{{{32 = 4C }}}

{{{C = 8 }}}

.=>… {{{H=3*8-6 }}}

{{{H=24-6 }}}

{{{H=18 }}}

Check:

{{{26 = 18+8 }}}

{{{26 = 26 }}}
