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.

ichiometric Calculations Practice Turn off Show units and Show numerical result. Press New question, and use what you have learned to solve another stoichiometry problem. For each problem, list the units given, the units asked for, and the solution. The problems in the Gizmo are given in random order, so you may have to press Next question several times to see a new problem. Note: Each term in the equation is either a solid (s), liquid (), gas (g), or an aqueous solution (aq). If you are stuck, try ode of the following hints: If the given unit is grams (or liters or particles), convert from that unit to moles first. Then, convert to moles of the answer substance. If the answer unit is grams, liters, or particles, find the number of moles of the answer substance first. Then, convert the moles of answer substance to the desired unit. If you have a calculator, try to calculate the solution to each problem yourself before turning on the Show numerical solution checkbox.
