mole of lactose x 6.023 x 10(>23) molecules (avagadro number)
0.148
One molecule has only one C atom.So 0.56mol has 0.56mol of C atoms
Lactose is a disaccharide composed of one glucose molecule bonded to a galactose molecule.
Since a water molecule, H2O, has exactly the same quantity of hydrogen atoms as a hydrogen molecule, H2, it follows that one mole of water can be decomposed into one mole of hydrogen gas.
A molecule is the fundamental unit of a compound. Therefore, a molecule of carbon dioxide is one C and two O atoms bonded together. A molecule is a single unit whereas a mole is a group of molecules and represents a fixed no. of any substance. Therefore, one mole of Carbon Dioxide consists of a 6.022 x 1023 molecules
228 molecules of ATP
Lactose, a sugar in milk, is composed of one glucose molecule joined by a glycosidic linkage to one galactose molecule. Lactose is classified as a disaccharide
Cows milk contains lactose (about 4.7%), which is a sugar molecule comprising one glucose molecule linked to one galactose molecule. Lactose is unique to milk. So, in one ounce of milk, approximately 1/20th of it would be 'sugar', i.e. lactose, about 1.5 g.
MolesOne mole is 6.02 × 1023 of anything. One mole of atoms is 6.02 × 1023 atoms, one mole of rice is 6.02 × 1023 grains, one mole of shoes is 6.02 × 1023 shoes. You get the picture? One mole of molecules is 6.02 × 1023 molecules.
Lactose is metabolized by the enzyme beta-galactosidase giving one molecule of galactose and one molecule of glucose.
6.022*10^23
One molecule has only one C atom.So 0.56mol has 0.56mol of C atoms
The answer is 4 moles.
Lactose is a disaccharide composed of one glucose molecule bonded to a galactose molecule.
because there are 2 hydrogen atoms in the molecule of hydrogen atoms
Since a water molecule, H2O, has exactly the same quantity of hydrogen atoms as a hydrogen molecule, H2, it follows that one mole of water can be decomposed into one mole of hydrogen gas.
The hydrogen molecule is diatomic, H2.
One mole of any molecule contains avogadro number of molecules. and that is equal to 6.023 X 1023
