Prof. Chon synthesized 12 g of a new compound, which has a molar mass 60 g/mol. Which will be true if Prof. Chon synthesizes 24 g of the same compound? The molar mass is still 60 g/mol, but the number of moles halves. The molar mass is now 120 g/mol, and the number of moles remains unchanged. The molar mass is still 60 g/mol, but the number of moles doubles. The molar mass is now 120 g/mol, and the number of moles doubles.

Concept explainers

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
