Interpretation:
The mass of 5 mole of iron (III) oxide (
Concept Introduction:
Mole is SI unit which is used to measure the quantity of the substance. It is the quantity of a substance which contains same number of atoms as present in accurately 12.00 g of carbon-12 is known as mole
Number of moles is defined as the ratio of mass to the molar mass.
The ratio of mass of the given compound to the number of moles of compound is known as molar mass.
The one mole of any substance is equal to the

- edict the major products of the following organic reaction: u A + ? CN Some important notes: • Draw the major product, or products, of the reaction in the drawing area below. • If there aren't any products, because no reaction will take place, check the box below the drawing area instead. Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are enantiomers. Explanation Check Click and drag to start drawing a structure.
