Question

A scientist wants to determine the percentage of α-D-mannose and β-D-mannose in an equilibrium solution. The specific rotation of α-D-mannose is +20.3°, while that of β-D-mannose is −17.0°. At equilibrium, the specific rotation is +14.2°. What are the percentages at equilibrium?

Accepted Answer

α-D-mannose: 84.6%; β-D-mannose: 15.4%

Answer

α-D-mannose: 36.4%; β-D-mannose: 65.6%

Answer

α-D-mannose: 49.1%; β-D-mannose: 50.9%

Answer

α-D-mannose: 73.7%; β-D-mannose: 26.3%
