Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

5) King Krator the Merciless has called on Pogo, a humble goldsmith, to make a crown for theKing. He gives Pogo exactly 14 oz of pure gold to fashion the crown and tells him that if hecheats the King, he will pay with his life ! Pogo leaves with the gold; he and his apprenticesspend two weeks in making the crown; finally he returns to the court. When Pogo returns withthe crown, King Krator finds that the crown weighs 397.25 grams, and has a volume of20.58cm3. King Krator asks the court wizard for the density of gold, and Wizard tells the Kingthat gold has a density of 19.3 times that of an equal volume of spring rain. Krator demands aslate, makes a few calculations, then sternly lifts his head to stare at Pogo. Does Pogo's headroll ?

The percent concentration of a solution is a ratio of the amounts of dissolved solute and solution, expressed as a percentage. The percent concentration of a solution can be written generally as % concentration = amount of solute x 100% amount of solution Depending on the situation, a percent concentration might be calculated for mass/mass, volume/volume, or mass/volume. tab os lock ntrol esc alt option Q A Z 5,566 2 W S AUG 2 F2 X H command 3 20 E F3 D $ 4 C 888 R Part A F4 70 Calculate the mass percent of a solution that is prepared by adding 54.8 g of NaOH to 461 g of H₂O.
