What mass of solid NaOH (97.0% NaOH by mass) is required to prepare 1.00 L of a 10.0% solution of NaOH by mass? The density of the 10.0% solution is 1.109 g/mL.
The present average concentration (mass percent) of magnesium ions in seawater is 0.13%. A chemistry textbook estimates that if 1.00 × 108 tons Mg were taken out of the sea each year, it would take one million years for the Mg concentration to drop to 0.12%. Do sufficient calculations to either verify or refute this statement. Assume that Earth is a sphere with a diameter of 8000 mi, 67% of which is covered by oceans to a depth of 1 mi, and that no Mg is washed back into the oceans at any time.

Without consulting your textbook, list and explain the main postulates of the kinetic molecular theory for gases. How do these postulates help us account for the following bulk properties of a gas: the pressure of the gas and why the pressure of the gas increases with increased temperature; the fact that a gas tills its entire container; and the fact that the volume of a given sample of gas increases as its temperature is increased.
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 ?

Concrete is prepared by roasting the mineral calcium carbonate, CaCO3, to drive off CO2 and produce calcium oxide, CaO. The chemical equation for this reaction is: CaCO3 ==> CaO + CO2 The Grand Coulee Dam on the Columbia River in Washington State was built using a volume of concrete of approximately 1.0 x 107 m3. If concrete has a density of 2.4 x 103 kg/m3, and assuming concrete is 100% by volume CaO, how much CO2 was released producing the concrete used to build the dam?
