Summary Introduction
To review:-
The molecular weight of water (H2O) and glucose (C6H12O6)
Introduction:
Molecular weight or molar mass is the total mass of a molecule. Molar mass does not depend on the size of the molecule of any sample and is an intensive property of the substance. The International System of Units (SI) of molar mass is kg/mol (kilogram per mole) but it is generally represented in g/mol (gram per mole).
