Suppose a 0.1M solution of a monosaccharide contains 1000 monosaccharide
seropon [69]

0.1 M solution of a disaccharide solution will contain 2000 monosaccharide molecules.

<h3>What are monosaccharides?</h3>

Monosaccharides, also known as simple sugars are the simplest monomers of carbohydrates which may either be 3 carbon, 4 carbon, 5 carbon, 6 carbon or 7 carbo compounds.

There are two types of monosaccharides;

  • aldoses sugars, e.g. glucose, and
  • ketose sugars e.g. fructose.

When two monosaccharides are linked together by glycosidic bonds to form a single compound, the compound formed is called a disaccharide.

Considering the give question:

Suppose a 0.1M solution of a monosaccharide contains 1000 monosaccharide molecules. How many monosaccharide molecules would be in a 0.1 M solution of a disaccharide.

The number of monosaccharides molecules present in the 0.1 M solution of a disaccharide is determined as follows:

1 disaccharide molecule contains 2 monosaccharide molecules

0.1M solution of a monosaccharide contains 1000 monosaccharide molecules.

0.1 M solution of a disaccharide will contain 2 * 1000 monosaccharide molecules

0.1 M solution of a disaccharide will contain = 2000 monosaccharide molecules.
