Get started for freeThe Kohinoor Diamond \(\left(d=3.51 \mathrm{~g} / \mathrm{cm}^{3}\right)\) is 108 carats. If one carat has a mass of \(2.00 \times 10^{2} \mathrm{mg}\), what is the mass of the Kohinoor Diamond in pounds? What is the volume of the diamond in cubic inches?
Potassium chloride is widely used in the manufacture of fertilizers. Its solubility is \(37.0 \mathrm{~g} / 100 \mathrm{~g}\) water at \(30^{\circ} \mathrm{C}\). At \(70^{\circ} \mathrm{C}\) its solubility is \(48.3 \mathrm{~g} / 100 \mathrm{~g}\) water. (a) Calculate the mass of potassium chloride that dissolves in \(44.5 \mathrm{~g}\) of water at \(30^{\circ} \mathrm{C}\). (b) Calculate the mass of water required to dissolve \(39.6 \mathrm{~g}\) of potassium chloride at \(70^{\circ} \mathrm{C}\). (c) If \(40.0 \mathrm{~g}\) of potassium chloride are added to \(75.0 \mathrm{~g}\) of water at \(30^{\circ} \mathrm{C}\), will it all dissolve? If the temperature is increased to \(70^{\circ} \mathrm{C}\), will it all dissolve? How many grams (if any) are undissolved at \(30^{\circ} \mathrm{C} ?\) at \(70^{\circ} \mathrm{C} ?\)
The following data refer to the compound water. Classify each as a chemical or a physical property. (a) It is a colorless liquid at \(25^{\circ} \mathrm{C}\) and \(1 \mathrm{~atm}\). (b) It reacts with sodium to form hydrogen gas as one of the products. (c) Its melting point is \(0^{\circ} \mathrm{C}\). (d) It is insoluble in carbon tetrachloride.
At what point is the temperature in \({ }^{\circ} \mathrm{F}\) exactly twice that in \({ }^{\circ} \mathrm{C} ?\)
The height of a horse is usually measured in hands. One hand is exactly \(1 / 3 \mathrm{ft}\) (a) How tall (in feet) is a horse of \(19.2\) hands? (b) How tall (in meters) is a horse of \(17.8\) hands? (c) A horse of \(20.5\) hands is to be transported in a trailer. The roof of the trailer needs to provide \(3.0 \mathrm{ft}\) of vertical clearance. What is the minimum height of the trailer in feet?
