Mixture problems involve combining two or more things and determining some characteristic of either the ingredients or the resulting mixture. For example, we might want to know how much water to add to dilute a saline solution, or we might want to determine the percentage of concentrate in a jug of orange juice. We can use fractions, ratios, or percentages to describe quantities in mixtures.

A 26.16 g mixture of zinc and sodium is reacted with a stoichiometric amount of sulfuric acid. The reaction mixture is then reacted with 304 mL of 1.65 M barium chloride to produce the maximum possible amount of barium sulfate. Determine the percent sodium by mass in the original mixture. mass percent Na=

Distillation is a purification technique for a liquid or a mixture of liquids. We utilize the difference in boiling points of liquids as a basis of separation. The core of a distillation process, is selective evaporation and condensation of particular components. Our overall goal is to evaporate and condense only one component from a mixture.
Buckley's Cough Syrup for Cough and Congestion Relief, Original Mixture
The creation of Buckley's Original Mixture was a classic case of recognizing a good thing. When pharmacist William Knapp Buckley took over a Toronto drugstore in 1919, he discovered several natural ingredients used in the treatment of coughs and colds. W.K. recognized the ingredients' merits and combined them to create a unique and effective.

Molar mass of a chemical is the mass, in grams, one mole that that chemical has. And it usually is in units of grams per mole, or g/mol. So here the molar mass of potassium chloride is 74.55 g/mol, which means that one mole of potassium chloride, 6.022x10^ (23) potassium chlorides, has a mass of 74.55 grams. Hope that helps.

Assuming all the $\ce{KClO3}$ decomposed to $\ce{KCl}$ and $\ce{O2}$, calculate the mass percent of $\ce{KClO3}$ in the original mixture." I took the amount of $\ce{O2}$, converted it to moles $\ce{O2}$, then divided it to moles of just O, then divived by 3, bcause for every 3 O (for the 3 in the $\ce{KClO3}$) there is a mole of $\ce{KClO3}$ so.

When the mixture is dissolved in water and an excess of silver nitrate is added, all the chloride ions associated with the original mixture are precipitated as insoluble silver chloride (AgCl). The mass of the silver chloride is found to be 2.1476 g. Calculate the mass percentages of sodium chloride and potassium chloride in the original mixture.

A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers. Each of the layers is called a phase. Figure 9.1.1 9.1. 1 : Oil and water do not mix, instead forming two distinct layers called phases. The oil phase is less dense than the water phase, and so.

Like a mixture, solutions can be separated into its original components. However, unlike mixtures, solutions can be separated by evaporation. For example: the water and salt solution will evaporate as the solution is heated. The water will change from liquid to gas as the water-salt solution begins to boil, leaving only the salt behind.
