(a)
Interpretation:
Amount of water that is brought and the money that is paid per liter of water has to be calculated.
(a)
Answer to Problem E.31E
The quantity of water brought is
Explanation of Solution
Mass of
The number of moles of
One mole of
Therefore, the mass of water present in
Thus the mass of water that is present is
The cost of
Cost of water:
The cost of water can be calculated by subtracting the price of
The quantity of water obtained is
Hence, the quantity of water brought is
(b)
Interpretation:
If the water is valued at zero cost, then the fair price of the hydrated compound,
(b)
Answer to Problem E.31E
Fair price of the hydrated compound will be
Explanation of Solution
The mass of water that is present is
The cost of
Hence, the fair price of hydrated compound is calculated as

Chemical Principles: The Quest for Insight
- In 1774, C. Scheele obtained a gas by reacting pyrolusite (MnO2) with sulfuric acid. The gas, which had been obtained that same year by Joseph Priestley by a different method, was an element, A. (a) What is the element isolated by Scheele and Priestley? (b) Element A combines with almost all other elements. For example, with cesium it gives a compound in which the mass percent of A is 19.39%. The element combines with hydrogen to give a compound with a mass percent of element A of 94.12%. Determine the formulas of the cesium and hydrogen compounds. (c) The compounds of cesium and hydrogen with element A react with one another. Write a balanced equation for the reaction.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_forwardChlorine exists mainly as two isotopes, 37Cl and 33Cl. Which is more abundant?
