Tentukan titik didih dan titik beku larutan 32 gram belerang begin mathsize 14px style open parentheses S subscript 8 close parentheses end style dalam 400 gram asam asetat. Asam asetat murni mendidih pada begin mathsize 14px style 118 comma 3 space degree C end style serta membeku pada begin mathsize 14px style 16 comma 6 space degree C end style dan tekanan 1 atm. begin mathsize 14px style left parenthesis K subscript b space C H subscript 3 C O O H space equals space 3 comma 1 space degree C space m to the power of negative sign 1 end exponent semicolon space K subscript f space C H subscript 3 C O O H space equals space 3 comma 6 space degree C space m to the power of negative sign 1 end exponent semicolon space italic A subscript r italic space S italic space equals 32 right parenthesis italic space end style

Jawaban:

Titik didih 32 g belerang dalam 400 g asam asetat,


begin mathsize 14px style space space space space space increment T subscript b double bond m middle dot K subscript b T subscript b bond T subscript b degree equals m subscript belerang over italic M subscript r space belerang end subscript cross times 1000 over m subscript asam space asetat end subscript cross times K subscript b T subscript b minus sign 118 comma 3 equals 32 over 32 cross times 1000 over 400 cross times 3 comma 1 T subscript b minus sign 118 comma 3 equals 7 comma 75 space space space space space space space space space space T subscript b equals 126 comma 05 space degree C end style 


Titik beku 32 g belerang dalam 400 g asam asetat,


begin mathsize 14px style space space space space space increment T subscript f double bond m middle dot K subscript f T subscript f degree minus sign T subscript f equals m subscript belerang over italic M subscript belerang cross times 1000 over m subscript asam space asetat end subscript cross times K subscript f 16 comma 6 minus sign T subscript f equals 32 over 32 cross times 1000 over 400 cross times 3 comma 6 16 comma 6 minus sign T subscript f equals 9 space space space space space space space space space space T subscript f equals 25 comma 60 space degree C end style 


Jadi, titik didih dan titik beku larutan 32 g belerang dalam 400 g asam asetat masing-masing adalah begin mathsize 14px style 126 comma 5 space degree C end style dan Error converting from MathML to accessible text..
