Concept explainers
(a)
Interpretation:
An approximate answer for the given calculation is to be stated. The ballpark answer is to be verified.
Concept introduction:
With experience, the answer to the chemical calculations can be estimated before using a calculator. After setting up the numerical calculation, each value is rounded off to one significant digit and the calculation is performed mentally. The resulting estimated answer is termed as ballpark answer as the value is only approximate.

- A student weighs out a 4.80-g sample of aluminum bromide, transfers it to a 100-mL volumetric flask, adds enough water to dissolve it, and then adds water to the 100-mL mark. What is the molarity of aluminum bromide in the resulting solution?arrow_forwardssume a highly magnified view of a solution of HCI that allows you to “see” the HCl. Draw this magnified view. If you dropped in a piece of magnesium, the magnesium would disappear, and hydrogen gas would he released. Represent this change using symbols for the elements, and write the balanced equation.arrow_forwardCalcium carbonate, CaCO3, can be obtained in a very pure state. Standard solutions of calcium ion are usually prepared by dissolving calcium carbonate in acid. What mass of CaCO3 should be taken to prepare 500. mL of 0.0200 M calcium ion solution?arrow_forward
- Each box represents a tiny volume in an aqueous solution of an ionic compound. (For simplicity, water molecules are not shown.) Which box represents: (a) Na2CO3, (b) NH4NO3, (C) CaBr2? Explain your reasoning.arrow_forwardYou wish to prepare 1 L of a 0.02-M potassium iodate solution. You require that the final concentration be within 1% of 0.02 M and that the concentration must be known accurately to the fourth decimal place. How would you prepare this solution? Specify the glassware you would use, the accuracy needed for the balance, and the ranges of acceptable masses of KIO3 that can be used.arrow_forward
