What is the difference between mass number and relative atomic mass?
Atomic mass is also known as atomic weight. Atomic mass is the weighted average mass of an atom of an element based on the relative natural abundance of that element’s isotopes. The mass number is a count of the total number of protons and neutrons in an atom’s nucleus.
What is absolute mass?
In an atom most of the space is vacant, thereby electrons, protons, and neutrons constitute the mass of the atom. Thus, the absolute mass of an atom is the mass of its subatomic particles i.e., the mass of the electrons + protons + neutrons.
What is average mass?
The average atomic mass (sometimes called atomic weight) of an element is the weighted average mass of the atoms in a naturally occurring sample of the element. Average masses are generally expressed in unified atomic mass units (u), where 1 u is equal to exactly one-twelfth the mass of a neutral atom of carbon-12.
How many moles of glucose does it contain?
1 molecule of glucose contains 6 atoms of C, 12 atoms of H, and 6 atoms of O • 1 mole of glucose contains 6 moles of C atoms, 12 moles of H atoms, and 6 moles of O atoms.
What is the mass g of glucose?
180.16 g/mol
What is the weight of glucose?
180.156 g/mol
Where does most of the mass of glucose come from?
Glucose is mainly made by plants and most algae during photosynthesis from water and carbon dioxide, using energy from sunlight, where it is used to make cellulose in cell walls, which is the most abundant carbohydrate. In energy metabolism, glucose is the most important source of energy in all organisms.
Does glucose have mass?
1 mole of glucose has a mass (its gram formula weight or molar mass) which is the sum of the gram atomic weights of all of the constituent atoms. 1 mole of H atoms weighs 1.01 g and there are 12 moles of H atoms in 1 mole of glucose, so the mass of hydrogen in 1 mole of glucose = 12 × 1.01 g = 12.12 g.

What does the C stand for in C6H12O6?
Glucose is a simple sugar with six carbon atoms and one aldehyde group. This monosaccharide has a chemical formula C6H12O6. It is also known as dextrose. It is referred to as aldohexose as it contains 6 carbon atoms and an aldehyde group. It can open in two forms, open-chain or ring structure.
