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.

Which of the following is true about finding the molar mass of potassium sulfate, K₂SO4? A. The molar mass is found by adding the molar mass of potassium (K) to the molar mass of sulfate (SO4). B. The molar mass is found by using Avogadro's number divided by 22.4. C. The molar mass is found by taking 2x the molar mass of potassium (K) plus 1x the molar mass of sulfur (S) plus 4x the molar mass of oxygen (O). D. The molar mass of potassium sulfate is a number between 1 and 10.
