12. Calculate the energy released, in kJ, when 1.00 mol U-238 isotopes (nuclear mass = 238.05078 amu) decays via a-particle emission to form thorium-234 (nuclear mass = 234.03596 amu). The nuclear mass of helium-4 is 4.002603 amu. The speed of light 2.997925×108 m/s and 1 amu = 1.660538×10-²4 g Answer: 1.10×10¹2 J or 1.10 x 10⁹ kJ =

The concentration of a solution equals the mass of what's dissolved divided by the total volume of the solution. Here's how the student prepared the solution: • The label on the graduated cylinder says: empty weight: 1.500 g • She put some solid sodium thiosulfate into the graduated cylinder and weighed it. With the sodium thiosulfate added, the cylinder weighed 96.6 g. She added water to the graduated cylinder and dissolved the sodium thiosulfate completely. Then she read the total volume of the solution from the markings on the graduated cylinder. The total volume of the solution was 97.7 mL. What concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant…
