Concept explainers
Interpretation:
The percent compositions of sodium oxide and sodium peroxide are to be determined with given mass of sodium and combined mass of sodium oxide and sodium peroxide.
Concept Introduction:
The percent composition is defined as the percentage by mass of each element in a compound.
The percentage of sodium in both the compounds is determined by the equation.
Here,
The molar mass of sodium is
The molar mass of
The molar mass of
The equation of total mass of the compound is as

- 4.104 When 2.750 g of the oxide Pb3O4 is heated to a high temperature, it decomposes to produce 0.0640 g of oxygen gas and 2.686 g of some new lead oxide compound. How can you use these data to determine the formula of the new compound?arrow_forwardAssume that the radius of Earth is 6400 km, the crust is 50. km thick, the density of the crust is 3.5 g/cm3, and 25.7% of the crust is silicon by mass. Calculate the total mass of silicon in the crust of Earth.arrow_forwardMany cereals are made with high moisture content so that the cereal can be formed into various shapes before it is dried. A cereal product containing 58% H2O by mass is produced at the rate of 1000. kg/h. What mass of water must be evaporated per hour if the final product contains only 20.% water?arrow_forward
- When an electric current is passed through an aqueous solution of NaCI, the valuable industrial chemicals H2(g), Cl2(g), and NaOH are produced. 2 NaCI(aq) + 2 H2O(l) H2(g) + Cl2(g) + 2 NaOH(aq) What mass of NaOH can be formed from 15.0 L of 0.35 M NaCI? What mass of chlorine is obtained?arrow_forwardNitric acid is produced commercially by the Ostwald process, represented by the following equations: 4NH3(g)+5O24NO(g)+6H2O(g)2NO(g)+O2(g)2NO2(g)3NO2(g)+H2O(l)2HNO3(aq)+NO(g) What mass of NH3 must be used to produce 1.0 106 kg HNO3 by the Ostwald process? Assume 100% yield in each reaction, and assume that the NO produced in the third step is not recycled.arrow_forward4.48 Elemental phosphorous is used in the semiconductor industry. It can be obtained from an ore called fluoroapatite via reaction with SiO2 and C: 4Ca5( PO4)3F+18SiO2+30C3P4+30CO+18CaSiO3+2CaF2 Suppose a particular semiconductor production plant requires 1500 kg of P4. If the recovery of P4 from this reaction is 73% efficient, what mass of fluoroapatite is needed?arrow_forward
