(a)
Interpretation:
The number of moles of platinum in the cone should be calculated.
Concept introduction:
The number of moles of a substance is related to molar mass of the substance as follows:
Here, m is mass and M is molar mass.
In 1 mol of a substance there are
Also, density of a substance is related to mass and volume as follows:
Here, m is mass and V is volume of the substance.
(b)
Interpretation:
The number of electrons in there in the cone should be calculated.
Concept introduction:
The number of moles of a substance is related to molar mass of the substance as follows:

How do you know?arrow_forward2-99 A 7.12 g sample of magnesium is heated with 1.80 g of bromine. All the bromine is used up, and 2.07 g of magnesium bromide is produced. What mass of magnesium remains unreacted?arrow_forward
- Elemental sulfur (1.256 g) is combined with fluorine, to give a compound with the formula SFx, a very stable, colorless gas. If you have isolated 5.722 g of SFx, what is the value of x?arrow_forwardConsider the following organic substances: ethanol, propane,hexane, and propanol. (a) Which of these molecules contains an OH group? (b) Which of these molecules containsthree carbon atoms?arrow_forward2a.arrow_forward
- 0.9 (a) Describe Rutherford's experiment and how it led to the structure of the atom. How was he able to estimate the number of protons in a nucleus from the scattering of the particles? (b) Consider the 2"Na atom. Given that the radius and mass of the nucleus are 3.04 X 10-1 m and 3.82 x 10-2 g, respectively, calculate the density of the nucleus in g cm. The radius of a 2Na atom is 186 pm. Calculate the density of the space occupied by the electrons in the sodium atom. Do your results support Rutherford's model of an atom? (The volume of a sphere is r, where r is the radius.)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? (b) If Pt costs$19/g, how many grams of Platinol can be made for $1.00 million(assume that the cost of Pt determines the cost of the drug)?arrow_forwardSome salts have water of hydration and are called hydrated salts. A 3.216 g sample of a hydrated salt of Na,B,O, · XH20 is heated to drive off the water of hydration. The resulting anhydrous salt, which has a mass of 2.222 g, contains 0.5077 g of sodium, 0.4775 g of boron, and some oxygen. What are the values of x, y, z and X in the above salt? Write the numerical values for x, y and z next to the symbol of the element, and X, before H20. Na H2O Barrow_forward
- Answer true or false. (a) Mendeleyev discovered that when elements are arranged in order of increasing atomic weight, certain sets of properties recur periodically.(b) Main-group elements are those in the columns 3A to 8A of the Periodic Table.(c) Nonmet.als are found at the top of the Periodic Table, metalloids in the middle, and metals at the bottom.(d) Among the US known elements,there are approximately equal numbers of metals and non metals.(e) A horizontal row in the Periodic Table is called a group.(f) The Group LA elements are called the "alkali metals"(g) The alkali metals react with water to give hydrogen gas and a metalhydroxide, MOH, where "M' is the metal."(h) The halogens are Group 7A elements.(i) The boiling points of noble gases (Group SA elements) increase goingfrom top to bottom of the column.arrow_forward(d) the ion with 74 electrons, 116 neutrons, and a +3 chargearrow_forwardAn atom of rhodium (Rh) has a diameter of about2.7 x 10-8 cm. (a) What is the radius of a rhodium atom inangstroms 1A° 2 and in meters (m)? (b) How many Rh atomswould have to be placed side by side to span a distance of6.0 μm? (c) If you assume that the Rh atom is a sphere, whatis the volume in m3 of a single atom?arrow_forward
