Web(a) Cu = 63.55 g (c) S = 32.07 g (b) Hg = 200.59 g (d) He = 4.00 g. Solution. Refer to the atomic masses in the periodic table inside the front cover of this textbook. State the mass of Avogadro’s number of atoms for each of the following elements: (a) Copper (c) sulfur (b) Mercury (d) helium WebSuppose that 0.323 g of an unknown sulfate salt is dissolved in 50 mL of water. The solution is acidified with 6 M \(\ce{HCl}\), heated, and an excess of aqueous \(\ce{BaCl2}\) is slowly added to the mixture resulting in the formation of a white precipitate.

WebLet's say you have a radioactive isotope that undergoes radioactive decay. It started from a mass of 67.0 g and it took 98 years for it to reach 0.01 g. Here's how you would determine its half-life: Starting from (1), we know that 0.01 = 67.0⋅ (1 2)98.0 t1/2 → 0.01 67.0 = 0.000149 = ( 1 2)98.0 t1/2 98.0 t1/2 = log0.5(0.000149) = 12.7 Web(6%) Problem 1: Suppose you had a 95 g piece of sulfur.

WebIf one piece is placed above another, the repulsive force can be great enough to support the top piece's weight. Assuming equal point charges (only an approximation), calculate the magnitude of the charge if electrostatic force is great enough to support the weight of a 10.0 mg piece of tape held 1.00 cm above another. WebThe atomic mass of sulphur is 32.1 grams per mole so we are gonna multiply the 1 electron for every 10 to the 12 atoms by the number of coulombs per electron so that's multiplying by negative 1.60 times 10 to the minus 19 coulombs per electron, the electrons cancel and then we want to know how many atoms are there in 100 grams of sulphur? WebWhat net charge would you place on a 100 g piece of sulfur if you put an extra electron on 1 in 10 12 of its atoms? (Sulfur has an atomic mass of 32.1.) Expert Solution & Answer ...
