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.
