Answer to Question #143253 in General Chemistry for Winters Francisco

Question

the reaction of 5 g oxygen with 5 g carbon monoxide produced 4.5 g methanol. what is the percent yield for the reaction 2H² + CO > CH³ OH

Answer 1

Theoretical mass of methanol:

m_t(CH₃OH)=m(CO)*Mr(CH₃OH)/Mr(CO)=5*32/28= 5.7 g;

Yield= m_a(CH₃OH)/m_t(CH₃OH) * 100%=4.5/5.7 *100% =78.95%

Ansewer:78.95%
