1kg of glucose produce 0.5kg of ethanol
ethanol
Ethanol will float
Sucrose is a double sugar and one molecule of sucrose is broken into one molecule of glucose and one molecule of fructose by the yeast (with and enzyme called invertase) prior to fermentation. From a pure chemical reaction perspective 1kg of can produce slightly more alcohol than 1kg of glucose, but given the right environment yeast can fully ferment both. Most brewers yeast prefers glucose to fructose so the glucose will be tend to be consumed first. Glucose is more expensive than sucrose so sucrose is a more cost effective choice.

1M glucose means that 1 mole of glucose is dissolved in 1kg of water. Since 1M means 1 molal. And molality is equla to no.of moles of solute per kg of water.
1kg = 1000g
The amount of weight gained is dependent on the amount of calories in a food, not the weight of the food itself. 3500 calories equals 1 lb, or .45 kg.
1kg of gold.
