Concept explainers
(a)
Interpretation:
Chemical formulas for ammonium phosphate, potassium nitrate and ammonium sulfate should be written.
Concept Introduction:
According to the laws of chemical combination, each substance may be described by a chemical formula that specifies the relative numbers of atoms of the elements in that substance. Percentage composition by mass of a particular substance is directly related to the empirical formula of that substance. The empirical formula of a compound can be simply related to the mass percentage of its constituent elements using the mole concept.
(b)
Interpretation:
Mass percentage of nitrogen, phosphorus and for each of the compounds in part (a) should be calculated.
Concept Introduction:
Percentage composition by mass of a substance is directly related to the empirical formula of that substance. The empirical formula of a compound can be simply related to the mass percentage of its constituent elements using the mole concept.

- Obtain an estimate for the number of atoms in the universe. Make the following assumptions: (a) All of the atoms in the universe are hydrogen atoms in stars. (This is not a ridiculous assumption because over threefourths of the atoms in the universe are in fact hydrogen. Gas and dust between the stars represent only about 15% of the visible matter of our galaxy, and planets compose a far smaller fraction.) (b) The sun is a typical star composed of pure hydrogen with a density of 1.4 g/cm^3 and a radius of 7x10^8 m. (c) Each of the roughly 100 billion stars in the Milky Way galaxy contains the same number of atoms as our sun. (d) Each of the 10 billion galaxies in the visible universe contains the same number of atoms as our Milky Way galaxy.arrow_forwardThe anticancer drug Platinol (Cisplatin), Pt(NH₃)₂Cl₂,reacts with the cancer cell’s DNA and interferes with its growth.(a) What is the mass % of platinum (Pt) in Platinol?
