Sugar dissolves in water physical change or chemical change

A sample of wine consists of water, sugar, some amount of ethyl alcohol, and grape juice. These ingredients blend together uniformly to give clear and tasty wine.

A compound has a percent composition of 24.74% potassium (molar mass = 39.10 g/mol), 34.76% manganese (molar mass = 54.94 g/mol), and 40.50% oxygen (molar mass = 16.00 g/mol).

What would be the saturation concentration (mole/L) of oxygen (O2) in a river in winter when the air temperature is 0°C if the Henry's law constant at this temperature is 2.28 * 10-3 mole/L-atm? What would the answer be in units of mg/L?
