If a grain of sugar is 200 micrograms (0.0002 grams), and there are 6.02*10^23 molecules in a mole (Avogadro's number, which is the number of particles in a mole), and the molecular weight of glucose is 180.1559 g/mol - First we find the number of moles in a grain of sugar, which is 0.0002 / 180.1559 or 0.0000011 moles per grain of sugar (really, per 200 micrograms). Then we multiply moles by 6.022*10^23 by the number of moles or 0.0000011 * (6.022*10^23) or...
6.62*10^17 molecules in a grain of sugar. (Again, really in 200 micrograms of glucose - a margin of error in weighing it could easily fluctuate that number by an order of magnitude)
Polysaccharides are large compounds made up of smaller units known as monosaccharides, which reflects the concept of how polymers are made up of smaller, single-unit structures called monomers, that combine together to form a larger, linked unit.
The amount of monosaccharides that form a polysaccharide highly depends on the structure itself; it may contain as few as 3 monosaccharides to as high a number we can think of; 2 monosaccharides would create a disaccharide, which is not a polysaccharide.
The amount of atoms that are in polysaccharides largely varies, but considering that most polymers are consisted of 6-carbon atom monosaccharides e.g., glucose, we can safely assume that the smallest polysaccharide would contain as little as 63 atoms to as high a number that you can think of.
The smallest number of glucose molecules needed in order to form a polysaccharide polymer is one. It is called a glyceraldehyde and consists of only three carbon atoms.
The number of glucose molecules is variable.

This smallest number is ten.
Glucose itself is a monomer of both sugar and starch. A monomer is a component of a polymer; in other words, many monomers come together to form a polymer. In the glucose example, many glucose molecules can come together to form complex carbohydrates- the polymer of glucose. Source: AP Biology

The answer is 4 moles.
How many monosaccharides are made up to make glucose molecule
glucose
Because glucose has many -OH groups, which are capable of forming hydrogen bonds with water molecules.
From one molecule of glucose (sugar) you can obtain two molecules of ethanol. Glucose's chemical composition is C6H12O6 Carbon dioxide (Co2) is lost in the fermentation process so we are left with 2C2H5OH or two ethanol molecules! Hope it helps!
There are many different types of sugar, but I will presume you mean glucose, C6H12O6. Glucose has a molecular mass of 180 g/mol. 12 g . 1 mol . 6.02 x 1023 molecules = 4.01 x 1022 molecules of glucose. 180g 1 mol
The simplest carbohydrate molecule is a sugar. For example, glucose. A single glucose (or any other simple sugar) is called a monosaccharide. A string of two joined sugar molecules (say 2 joined glucoses) forms a disaccharide. Many thousands of sugar molecules joined into a very long string is what a polysaccharide is. Starch is a plant-stored polysaccharide and glycogen is an animal-stored polysaccharide. These are examples of very long strings of alpha glucose molecules. A long string of beta glucoses forms the polysaccharide called cellulose.

As many as 1,000 glucose units can be stacked together to form one starch unit.
they are cellulose molecule.starches
Many
glucose is a type of sugar, and it is combined with starch. sugar is a category, because it could be fructose, glucose, etc.
Cellulose has more chemical bonds. It consists of many glucose molecules joined together. However we don't usually think of cellulose as a sugar. It is more properly called a polysaccharide.
