Concept explainers
Interpretation:
A concept map must be designed that illustrates the mole concept.
Concept introduction:
Mole is the amount of any substance which contains
Answer to Problem 203A
A concept map to illustrate mole concept is given below:
Explanation of Solution
As can be seen from the concept, 1 mol of any substance contains Avogadro’s number of units which can be atoms, molecules, ions etc.
The mass of 1 mol substance is known as molar mass.
Empirical formula is the smallest repeating unit of the molecule. Molecular formula contains certain number of the empirical formula units.
From % composition of elements empirical formula can be found. % composition is the amount of all the constituent elements in the compound.
Mole is the amount of any substance which contains Avogadro’s number of units.

- " is The structure of the bicarbonate (hydrogen carbonate) ion, HCO3-, HCO3 best described as a hybrid of several contributing resonance forms, two of which are shown here. HO :0: :Ö: HO + Bicarbonate is crucial for the control of body pH (for example, blood pH: 7.4). A more self-indulgent use is in baking soda, where it serves as a source of CO2 CO₂ 2 gas, which gives bread and pastry their fluffy constituency. (i) Draw at least one additional resonance form. = (ii) Using curved "electron-pushing" arrows, show how these Lewis structures may be interconverted by movement of electron pairs. (iii) Determine which form or forms will be the major contributor(s) to the real structure of bicarbonate, explaining your answer on the basis of the criteria in Section 1-5.arrow_forwardWhich of these is the best use of a volumetric flask? measuring how much liquid it contains delivering a precise amount of liquid to another container holding solutions making solutions of precise concentrationarrow_forwardYou're competing on a Great British television game show, and you need to bake a cake.
