in D-GLUCOSE 'D' does not mean dextrose (for dextro we use small 'd') it is a series of monosaccharides in which a 'OH' group attached to C-5 is shown at right side of vertical carbon chain.
D stands for 'dexter' which means "right" as in right handed. The opposite is L for "laevus" or left handed. When used in the context of chemistry, chirality usually refers to molecules. Two mirror images of a molecule that cannot be superimposed onto each other are referred to as enantiomers or optical isomers. Because the difference between right and left hands is universally known and easy to observe, many pairs of enantiomers are designated as "right-" and "left-handed." A mixture of equal amounts of the two enantiomers is said to be a racemic mixture.
These are two sugar molecules which have the same formula (which is to say, the same number of each type of element per molecule) but have a slightly different geometrical arrangement; they are mirror images of each other. They can be identified by their effect on polarized light. One form causes polarized light to rotate clockwise (D for dextro-rotary), and one form causes it to rotate counterclockwise (L for levo-rotary) when the light is reflected by that compound. This phenomenon known as stereo-isomerism, and it was originally discovered by Antoine Lavoisier, the founder of chemistry, in his studies of racemic acid.
Your question is not specific enough - what do you mean by isomer? If you mean stereoisomers (likely question with biomolecules) the two most common stereoisomers of glucose are L-glucose and D-glucose. There are 4 chiral carbons in glucose so there would be 42 or 16 possible stereoisomers. The other most important stereoisomers would be mannose and galactose.
The answer is 90,08 g glucose.
The solubility of glucose in water at 25 oC is only 909 g/L.
2 moles in 2 liters means 1 mole in 1 liter - so it its molarity is 1.
I2(l) + H2O(l) -> OI-(aq) + 2H+(aq) + I-(aq)
For one, dextrose and glucose are both monomers, or to be specific, monosaccharides. Dextrose and glucose are essentially the same thing, except that dextrose is specifically D-glucose. There exists two stereoisomeric forms of glucose, being D-glucose and L-glucose. "D" refers to "right" and "L" refers to "left". Essentially stereoisomeric means that D-glucose and L-glucose are mirror images of each other. T The difference between L-glucose and R-glucose is that L-glucose cannot be metabolized during glycolysis which is a component of cellular respiration.
d-glucose is called dextrose, l-glucose is called levose

According to the Fischer projection formula, they are enantiomers.

Apparently L-glucose tastes the same and is not metabolized; however it is expensive to manufacture and hence not likely to be used as a sweetener.
I hope you mean blood glucose tolerance, which should be between 3.5mml/l to 6mml/l. These levels are for a non diabetic patient (normal person)
The answer is 90,08 g glucose.
Glucose, the chemical that plants produce for food, is a monosaccharide.
An 84 blood glucose is perfect.
sucrose is a unique chemical compound containing a glucose and fructose unit (both of which exhibit chirality) connected by an alpha/beta linkage. in nature all sugar units are comprised of dextrorotary molecules. As far as synthetic manufacture is concerned there are 4 potential anaolgues of sucrose consisting of :d-d glucose/fructose, L-D glucose/fructose, D-L glucose/fructose, and L-L glucose/fructose
The concentration is 69,3 g/L.
