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)
What else can I help you with?
Is glucose a type of starch?
No, glucose is a simple sugar, while starch is a complex carbohydrate made up of many glucose molecules bonded together.
What are the difference between glucose starch and sugar?
Glucose is a simple sugar and the primary source of energy for our cells. Starch is a complex carbohydrate made up of many glucose molecules linked together, found in plants as a storage form of energy. Sugar is a broad term that includes both simple sugars (like glucose) and disaccharides (like sucrose), which are used as sweeteners in food.
What is the structural differences between glucose and starch?
Glucose is a monosaccharide (simple sugar) having the formula C6H12O6. D-glucose has 5OH, 1H and 1O functional groups. Starch is polymer of Glucose. It is made of many Glucose molecules attached by Glycosidic bonds. The formula is (C6H10O5)n, where n represents number of substitutions.
What is the difference between sugar and glucose?
Sugar is a broad term that refers to a group of carbohydrates, including simple sugars like glucose, fructose, and sucrose. Glucose is a type of sugar that is the main source of energy for the body's cells and is found in many foods. So, all glucose is sugar, but not all sugar is glucose.
What is the monomer of glucose?
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
Is glucose a starch?
No, glucose is a simple sugar and the main source of energy for our bodies. Starch is a complex carbohydrate made up of many glucose molecules bonded together.
What like glycogen and starch are made by joining many sugar molecules together?
glucose
Is glucose a type of starch?
No, glucose is a simple sugar, while starch is a complex carbohydrate made up of many glucose molecules bonded together.
Why does glucose dissolves in water?
Because glucose has many -OH groups, which are capable of forming hydrogen bonds with water molecules.
How many simple sugar molecules can be stacked together to make starch?
As many as 1,000 glucose units can be stacked together to form one starch unit.
How many molecules of ethanol can be obtained from one molecule of sugar?
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!
How many microns are in a grain of sugar?
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

Sugar is a broad term that includes both simple sugars (like glucose) and disaccharides (like sucrose), which are used as sweeteners in food.
What are polysaccarhides?
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.
How many simple sugar molecules make up one molecule of surcrose?
One molecule of sucrose is composed of one molecule of glucose and one molecule of fructose, which are both simple sugar molecules.
What are the differences between starch and glucose?
glucose is a type of sugar, and it is combined with starch. sugar is a category, because it could be fructose, glucose, etc.
How many molecules of water would be used to form two molecules of glucose?
12 molecules of water would be used to form two molecules of glucose. This is because the chemical formula for glucose is C6H12O6, and the process of forming glucose from water involves 6 molecules of water for each carbon atom.
